title: Survey of the Low-Redshift Intergalactic Medium with HST/COS ("IGM")

description: A survey of the low-redshift intergalactic medium (IGM) has been performed by Danforth et al. (2015). Using HST COS spectra of 82 UV-bright AGN, several thousand absorption lines are identified from 2,610 distinct redshift systems at z &lt; 0.723. The spectral features were selected and measured using a semi-automated analysis to minimize bias in line identification. For each of the 82 sightlines, a coadded, continuum-fitted spectrum is provided in FITS format. Two catalogs for each sightline are presented: one catalog lists the identified spectral features sorted by wavelength, while another lists the absorption features associated with IGM systems sorted by redshift.

title: HST Snapshots of 3CR Radio Galaxies ("3CR")

description: The revised 3C catalogue (3CR, Bennett 1962) forms a flux-limited sample of the most radio-powerful sources in the northern hemisphere. Over the decade and a half of HST operation, a snapshot imaging survey from the near-IR to the near-UV of a large number of these sources has been conducted. Most recently the team has completed a NICMOS 1.6 micron survey of low-redshift (z&lt;0.3) 3CR sources (Madrid et al. 2006, Floyd et al 2008). The fully-reduced data for all 101 sources included in those papers are presented here in numerical order. This includes 90 sources from the SNAP survey and a further 11 from the NIC2 archive.

title: An ACS Treasury Survey of the Coma Cluster of Galaxies ("COMA")

description: The HST ACS Coma Cluster Treasury Survey is a deep, two-passband imaging survey of one of the nearest rich clusters of galaxies, the Coma cluster (Abell 1656, HST Proposal 10861).  While HST data were obtained with both the ACS and NICMOS instruments, only the ACS data are included in this release. The survey was designed to cover an area of 740 square arcmin in regions of different density of both galaxies and intergalactic medium within the cluster. The ACS failure of January 27th 2007 left the survey 28% complete, with 21 ACS pointings (230 square arcmin) completed, and partial data for a further 4 pointings (44 square arcmin).

title: Legacy ExtraGalactic UV Survey ("LEGUS")

description: LEGUS is a Treasury Program that imaged 50 local (closer than 12 Mpc) galaxies in multiple colors with WFC3 and ACS. Because of the proximity of all targets, the galaxies will be resolved into their main components: stars, star clusters, and associations.  Mosaic images as well as source catalogs are provided.

title: An Atlas of HST Ultraviolet Images of Nearby Galaxies ("MAOZ")

description: This High Level Science Product consists of a pictorial atlas of UV (2300 Angstrom) images, obtained with the Hubble Space Telescope Faint Object Camera, of the central 22×22 arcseconds of 110 galaxies ( Maoz et al. 1996).  The observed galaxies are an unbiased selection constituting about one half of a complete sample of all large (D&gt;6 arcmin) and nearby (V&lt; 2000 km/s ) galaxies.  The team measured the integrated ~2300 Angstrom flux in each image, and classified the UV morphology. The UV and optical parameters are given in the tables provided.
DOI: 10.17909/t9sg6v
title: K2 Variability Catalog ("K2VARCAT")

description: The lightcurves from K2 contain larger systematics than the original Kepler mission, due to the reduction in pointing precision as a result of having to rely on only two reaction wheels. Armstrong et al. have created a technique to correct for the pointing-dependent nature of the pixel-level fluxes. The team have released their extracted lightcurves (using a photometric aperture defined by the brightness of the target), as well as three plots of the resulting lightcurves: extracted, detrended, and phase-folded.  The team has also released a catalog of object classification derived using supervised and unsupervised machine learning.

title: Hubble Ultra Deep Field 2009 ("HUDF09")

description: Hubble Ultra Deep Field 2009 (HUDF09) program observations, obtained as HST program 11563 (PI: Garth Illingworth) in Cycle 17. The program uses WFC3/IR as the prime instrument for 192 orbits to image the deep ACS fields that were obtained in the original HUDF (PI: Steven Beckwith) program and in the HUDF05 (PI: Massimo Stiavelli) program.
DOI: 10.17909/t9x594
title: FUSE Survey of Cataclysmic Variables ("FUSE_CV")

description: The FUSE Survey of Cataclysmic Variables (Froning et al. 2009) contains 178 FUSE observations of 99 targets. For each dataset, the data products were examined (images of the count rate and aperture placement for each exposure and extracted spectra for each observation) to identify any problems with the observation and to ensure that the pipeline correctly screened out bad time intervals. For time-tag data, the individual exposures in each segment were combined using the Calfuse tool 'ttag_combine'. Then the eight time-averaged segment spectra were combined into a single broadband spectrum using the IDL-based tool 'fuse_analysis' provided on the FUSE website. Using the overlapping wavelength regions, the spectra were cross-correlated to correct for small wavelength offsets between channels and then combined the spectra, weighting by the error bars in each channel. Bad spectral regions were screened out as needed. The time-averaged spectra were binned to 0.1 Angstroms. Finally, spectra from different observations were combined if they were acquired close in time and if there were no gross changes in the spectrum between observations. The survey is described in the paper by Froning et al. 2012.

title: Galaxy Evolution from Morphologies and SEDs ("GEMS")

description: GEMS is a large-area (800 arcmin^2) two-color (F606W and F850LP) imaging survey with the Advanced Camera for Surveys on the Hubble Space Telescope. Centered on the Chandra Deep Field-South, it covers an area of ~ 28'x28', or about 120 HDF areas, to a depth of MAB(F606W) = 28.5(5-sigma) for compact sources. In its central ~1/4, GEMS incorporates ACS imaging from the GOODS project. Focusing on the redshift range ~ 0.2 &lt; z &lt; 1.1, GEMS provides morphologies and structural parameters for nearly 10,000 galaxies where redshift estimates, luminosities, and SEDs exist from COMBO-17. At the same time, GEMS contains detectable host galaxy images for several hundred faint active galactic nuclei. The science goals, the experiment design, the data reduction, and science analysis plan for GEMS are described in Rix et.al. (2004).

DOI: 10.17909/t97g6w
title: NICMOS Legacy Archive PSF Library (LAPL) And Cirumstellar Environments ("LAPLACE")

description: NICMOS coronagraphy, with well-matched template Point Spread Function  subtraction, probes the closest environments of occulted targets with the  highest imaging sensitivity in intrinsically high contrast fields at the smallest radial distances afforded.  To obtain the best results, suitable template  PSFs required to produce high-fidelity, photometrically robust, high contrast coronagraphic images are needed. To remedy this situation, the team undertook a rigorous, homogeneous, and complete recalibration and analysis of the full archival set of raw NICMOS coronagraphic images (through HST Cycle 15) to create a Legacy library of template PSFs.

title: HST/GHRS Spectral Atlas of the M2 Iab Star Alpha Orionis ("ATLASALPHAORI")

description: ATLASALPHAORI is an ultraviolet atlas of Alpha Orionis (Betelgeuse) constructed by members of the HST Goddard High Resolution Spectrograph (GHRS) scientific development and calibration teams. This star was chosen because of extensive observations of it from ground-based spectrographs, photometers, and interferometers in the optical and IR spectral regions and because of the time coverage of its variations from ground sites and the IUE satellite by many observers.  The spectral data were recorded on 1992 Septmber 24 using the GHRS Small Science Aperture (SSA).  The atlas includes a number of plots of relative flux versus wavelength over the range 1979 to 3300 Angstroms.  The data also include two-column ASCII files listing the wavelengths (in Angstroms) and flux (in units of 10^9 ergs cm^2/s/Angstrom).

title: HST/GHRS Observations of the HgMn Star chi Lupi ("CHILUPI")

description: A major, eight-year investigation of the extraordinarily detailed ultraviolet spectrum of the sharp-lined, non-magnetic, main-sequence chemically peculiar star chi Lupi (B9.5pHgMn + A2Vm) was undertaken as a GHRS GTO team project. The UV observations are comprised of 345 Angstroms of the spectrum acquired with the Goddard High Resolution Spectrograph on board the HST, at an average resolution of 0.023 Angstroms.  The team provides an online version of their reduced data, as well as the synthetic spectra and line identification lists used to produce the figures in Brandt et al. (1999).

DOI: 10.17909/t9v885
title: Hubble Infrared Pure Parallel Imaging Extragalactic Survey ("HIPPIES")

description: HIPPIES utilizes long-duration pure parallel visits (~&gt; 3 orbits) of HST at high Galactic latitude (|b| &gt; 20 degrees) to take deep, multi-band images in WFC3 (since Cycle 17) and in ACS (starting Cycle 18).  HIPPIES relased its best-effort, high-level image products derived from all these three programs (PIDs 11702, 12286; and 11700) after each set (i.e., field) of observations were finished, using the best HST reference files available at the time of data reduction.  HIPPIES DR1 only involves the data taken in Cycle 17 by programs 11702 and 11700. These two programs used both the infrared (IR) and the UV-optical (UVIS) channels of WFC3. The IR images were taken in the same three bands in both programs, namely, F098M, F125W and F160W. Program 11702 used F600LP, while program 11700 used F606W. A few fields were observed by both programs, and thus have UVIS images in both F600LP and F606W.

title: Deep HST ACS Imaging of 47 Tuc and the SMC ("DEEP47TUC")

description: Kalirai et al. have observed the globular cluster 47 Tucanae for 121 orbits using the Advanced Camera for Surveys. These extremely deep images were taken in two filters: F606W (broad V-band) and F814W (I-band). Using these observations, Kalirai et al. were able to construct one of the deepest and most complete color-magnitude diagrams of a stellar population, probing down to 30th magnitude and extending from the faintest end of the main sequence to the coolest white dwarf members. As an added bonus, members of the Small Magellanic Cloud represent background sources, and these observations are able to resolve SMC targets down to 0.2 solar masses.  The team have released their stacked ACS mosaics (FITS files), source catalog (ASCII text table), and artificial source lists (ASCII text table) used for testing photometry, astrometry, and completeness, as High Level Science Products.

title: ACS Nearby Galaxy Survey ("ANGST")

description: The ACS Nearby Galaxy Survey (ANGST) team undertook a systematic, complete, and carefully crafted imaging survey of all galaxies in the Local Universe outside the Local Group (GO-10915, DD-11307; PI:Dalcanton). The set of HLSP include binary FITS tables of photometry for the ANGST sample as defined in Dalcanton et al. 2009. Also included are associated reference images and raw photometry tables.
DOI: 10.17909/t9b88h
title: An Atlas of Recalibrated HST FOS Spectra of Active Galactic Nuclei and Quasars ("FOS_AGN")

description: The FOS_AGN atlas provides spectral FITS data and preview files for all successful pre-COSTAR spectra using the Faint Object Spectrograph of AGNs (Active Galactic Nuclei). A discussion of the uniform flux and wavelength calibrations of these spectra, including common instrumental artifacts that can appear in FOS data, is given in Evans and Koratkar (2004). The data list includes 221 AGNs. Where possible, and in most cases, these spectra have been clipped at overlapping wavelengths and merged to form a panchromatic spectrum. The target list was compiled from a PI object description in the keywords denoted by 'AGN', 'quasar', 'Seyfert', etc., as well as others designated by the PI as 'galaxy' that should fit into these categories.

title: Howell-Everett UBV Photometric Survey of the Kepler Field ("KPLRUBV")

description: The Howell-Everett Kepler Field UBV Survey contains a list of 4,414,002 sources observed in a survey of the NASA Kepler Mission field using Johnson/Harris U, B, and V filters in the NOAO Mosaic1.1 Camera at the WIYN 0.9m Telescope on Kitt Peak. The survey data were taken from 206 slightly-overlapping pointings that cover 191 square degrees in each of the three passbands. The area covered includes almost the entire Kepler field plus areas between the Kepler CCDs and around the perimeter of the field.  The survey is estimated to be complete to magnitudes as faint as U~18.7, B~19.3, and V~19.1, but varies with location. The mean bright limits for point sources are U=10.1, B=10.6 and V=10.5.

title: Calibrated First-Order HUT Spectra of White Dwarfs G191-B2B and HZ 43 ("HUT-WDS")

description: During the Astro-1 mission, an aluminum filter was used to block first-order light, and two white dwarfs (G191-B2B and HZ 43) were observed in second order. The flux from these second-order observations were then subtracted from the first-order spectra of these two objects. This was the only time that such second-order corrections were applied to HUT spectra, because no second-order observations were obtained during Astro-2.  Because these spectra are in a different format compared to the rest of the HUT data products on MAST, they are provided here as an HLSP.

title: Pre-Main Sequence Stars: IUE Spectral Atlas ("IUEPMS")

description: This spectral catalog contains coadded IUE low-resolution spectra (from standard NEWSIPS MXLO files) of every T Tauri star (TTS) and candidate Herbig Ae/Be (HAEBE) star with useful IUE data. Processing and analysis procedures are described in Valenti, Johns-Krull, & Linsky (2000) for short wavelength (SW) data (1150-1980 Angstroms) and in Valenti, Fallon, and Johns-Krull (2003) for long wavelength (LW) data (1900-3200 Angstroms).  The dereddened main-sequence templates used in the analysis of HAEBE stars are also presented.  Coadded SW and LW spectra have been spliced together, when both are available, using the full extent of the lower noise SW segment.

title: Dusty Interacting Galaxy GADGET-SUNRISE Simulations ("DIGGSS")

description: DIGGSS is a database of simulated galaxy merger images and associated 'data' products. These simulations were created and analysed with the support of HST Theory Programs 9515, 10678 (PI Joel Primack), 10958, and 11759 (PI Patrik Jonsson).  The galaxy merger simulations were produced by the N-body/SPH code GADGET (Springel & Hernquist 2002). For the details of the GADGET simulations, please refer to Cox et al. 2006, 2008.  The GADGET simulations were then processed through the Monte-Carlo radiative transfer code SUNRISE (v2) to produce mock SDSS-g band images at 11 different viewing angles, including the effects of dust and new star-formation. For details of the SUNRISE code, please refer to Jonsson 2006.  Finally, the mock SDSS g-band images were convolved with a PSF and added to noise map to simulate real observations. The non-parametric morphologies (Gini coefficient, M_20, Asymmetry, Concentration, Petrosian radii) and projected galaxy separations of the final images were measured by Lotz et al. 2008, 2010a, 2010b. For definitions of the non-parametric morphologies, please refer to Lotz et al. 2004.

title: HST Observations Of Comet C/2012 S1 ("ISON")

description: A comprehensive set of Hubble Space Telescope (HST) observations of Comet ISON.  Hubble Heritage program 13229 imaged the comet on 8 May 2013, using a Wide Field Camera 3 (WFC3) subarray which is half of one of the two CCDs (2K x 2K subarray). Eight identical 171-second exposures were obtained, with one dither step to mitigate bad pixels. The long-pass F350LP filter was used to maximize the signal-to-noise in one orbit. A small offset from the nominal aperture was applied to optimally position the comet and tail within the field of view.  Another orbit on 30 April 2013 obtained deep fixed-pointing images of a field with Comet ISON in it, released July 16, 2013. Further details about the Heritage Comet ISON observing program are contained in the Phase II observing program.

title: HST Treasury Program on Eta Carinae ("ETACAR")

description: Kris Davidson is the PI for an HST Treasury Program that observed Eta Carinae. Two HST programs were associated with this project: 9420 and 9973. Data from other programs have also been included for the creation of this data set, including: 7302, 8036, 8327, 8483, 8619, 9083, and 9337.  The project has produced a series of technical memorada that detail processing techniques, definitions, mathematical considerations and other details.  Although the treasury program was designed to obtain data during an anticipated spectroscopic event in mid-2003, this star and its ejecta have unique characteristics that make them important to several branches of astrophysics. Observations were obtained using the HST STIS/CCD, STIS/MAMA, WFCP2 and ACS images. Currently only the STIS/CCD observations have been released by the team.

title: Hubble Heritage Project ("HERITAGE")

description: The Hubble Heritage Project and MAST maintain this repository of high-level science products associated with some of the Heritage press releases. These are the scientific data (in FITS format) used to create the Heritage color composite press release images. The data has been expertly prepared, significantly beyond the standard pipeline processing. This usually involves careful image registration, combination, and cleaning via drizzling, making it a ready for further scientific analysis and educational use. These data are typically made available at the time of the associated press release, and each include a README file with data reduction details. Their inclusion as MAST High-Level Science products (HLSP) also means these data can be found via MAST archive queries.

title: Hubble Helix Observations ("HELIX")

description: For the 14 hours of peak Leonid meteoroid flux in November 2002, the Hubble Space Telescope was pointed away from the radiant, and the solar arrays were oriented to minimize their cross-section. By coincidence, one of the nearest and largest planetary nebulae, the Helix Nebula (NGC 7293), was nearly opposite the incoming Leonids and could be observed. A Hubble Helix Team of volunteers, led by Margaret Meixner (STScI), organized a nine-orbit campaign to observe the Helix with the ACS, WFPC2, NICMOS, and STIS.  A contiguous 3x3 grid of 4k by 4k-pixel ACS images covering much but not all of the Helix was exposed in two filters, Ha+[N II] (F658N) and [O III] (F502N). The WFPC2 images, obtained in parallel, covered portions of the nebula in [O I] (F631N), He II (F469N), or Ha (F656N). NICMOS/NIC3 observations were obtained at two locations on the nebula and two off NICMOS/NIC3 observations were obtained at five locations on the nebula and four off. A few of the STIS parallel observations in [O II] (F28X50OII) were located on the nebula, but most were located off the nebula.
