ROSAT Catalog PSPC WGA Sources

WGACAT is a point source catalog generated from all ROSAT PSPC pointed observations. This catalog has been generated by N.E. White (HEASARC/GSFC), P. Giommi (SDC/ASI) and L. Angelini (HEASARC/GSFC) and is a private research effort, not related to the official catalogs generated by the ROSAT project. The WGACAT was made first publicly available in November 1994 through the HEASARC on-line service (White, Giommi and Angelini 1994), with a first minor revision in March 1995 (WGACAT95 hereafter). It was generated using all the public ROSAT PSPC pointed data available than, corresponding to 75 % of the entire set, and featured ~ 68000 detections of which 62000 were unique sources. The current version, released in May 2000 (see also the update section), is the final and complete version of WGACAT and includes the remaining sequences not processed in the WGACAT95. WGACAT (May 2000) contains about 88,000 detections, with more than 84,000 individual sources, obtained from 4160 sequences. The catalog was generated using an optimized sliding cell detect algorithm in XIMAGE (first developed for the EXOSAT project). The inner and outer parts of the images were run separately, to maximize the sensitivity to source detection. This method is very sensitive in finding point sources, but can also find spurious sources where there is extended emission. We have visually inspected each detection, removed the obvious spurious cases and assigned a quality flag to each detection. This is a service provided by NASA HEASARC .

M 31 Revised Bologna Clusters and Candidates Catalog (Version 5)

The Revised Bologna Catalogue of M 31 globular clusters and candidates (RBC, V.5, August 2012) lists all the confirmed globular clusters (GCs), all the known candidates GCs, and also all the objects that were identified as candidate GCs in the past and were subsequently recognized not to be genuine clusters, each entry being properly classified (GC, candidate GC, foreground star, background galaxy, HII region, etc.). The latter entries are maintained in the catalog to avoid re-discoveries of objects that may look like M 31 GCs and have been already classified as non-GCs. Please take into account the classification flag(s) when you use the RBC. Please acknowledge the use of this catalog. The proper reference is: Galleti S., Federici L., Bellazzini M., Fusi Pecci F., Macrina S. &quot;2MASS NIR photometry for 693 candidate globular clusters in M 31 and the Revised Bologna Catalogue (V.1.0)&quot;, Astron.&amp;Astrophys., 2004, 416, 917 (2004A&amp;A...416..917G) This table was created by the HEASARC in November 2014 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/V/143"&gt;CDS Catalog V/143&lt;/a&gt; file rbc5.dat, Version 5 of the Revised Bologna Catalogue of M 31 globular clusters and candidates.

Combined space stressors induce independent behavioral deficits predicted by early peripheral blood monocytes (Behavioral Assays)

Interplanetary space travel poses many hazards to the human body. To protect astronaut health and performance on critical missions, there is first a need to understand the effects of deep space hazards, including ionizing radiation, confinement, and altered gravity. Previous studies of rodents exposed to a single such stressor document significant deficits, but our study is the first to investigate possible cumulative and synergistic impacts of simultaneous ionizing radiation, confinement, and altered gravity on behavior and cognition. Our cohort was divided between 6‐month‐old female and male mice in group, social isolation, or hindlimb unloading housing, exposed to 0 or 50 cGy of 5 ion simplified simulated galactic cosmic radiation (GCRsim). We report interactions and independent effects of GCRsim exposure and housing conditions on behavioral and cognitive performance. Exposure to GCRsim drove changes in immune cell populations in peripheral blood collected early after irradiation, while housing conditions drove changes in blood collected at a later point. Female mice were largely resilient to deficits observed in male mice. Finally, we used principal component analysis to represent total deficits as principal component scores, which were predicted by general linear models using GCR exposure, housing condition, and early blood biomarkers. This dataset derives results from the behavior assays Balance Beam, Elevated Plus Maze, Open Field, Three Chamber Social Approach, Novel Object Recognition, and Radial Arm Water Maze using the same source animals as the flow cytometry blood samples in OSD-640.

AEGIS-X Deep Survey Chandra X-Ray Point Source Catalog

This table is based on the results of deep Chandra imaging of the central region of the Extended Groth Strip, the AEGIS-X Deep (AEGIS-XD) survey. When combined with previous Chandra observations of a wider area of the strip, AEGIS-X Wide (AEGIS-XW), these provide data to a nominal exposure depth of 800ks in the three central ACIS-I fields, a region of approximately 0.29 deg&lt;sup&gt;2&lt;/sup&gt;. This is currently the third deepest X-ray survey in existence; a factor ~2-3 shallower than the Chandra Deep Fields (CDFs), but over an area ~3 times greater than each CDF. This table contains a catalog of 937 point sources detected in the deep Chandra observations, along with identifications of the X-ray sources from deep ground-based, Spitzer, GALEX, and Hubble Space Telescope imaging. Using a likelihood ratio analysis, the authors associate multiband counterparts for 929/937 of their X-ray sources, with an estimated 95% reliability,making the identification completeness approximately 94% in a statistical sense. Reliable spectroscopic redshifts for 353 of the X-ray sources are available predominantly from Keck (DEEP2/3) and MMT Hectospec, so the current spectroscopic completeness is ~38%. For the remainder of the X-ray sources, the authors compute photometric redshifts based on multiband photometry in up to 35 bands from the UV to mid-IR. Particular attention is given to the fact that the vast majority of the X-ray sources are active galactic nuclei and require hybrid templates. The photometric redshifts have a mean accuracy sigma = 0.04 and an outlier fraction of approximately 5%, reaching sigma = 0.03 with less than 4% outliers in the area covered by CANDELS. The new AEGIS-XD Chandra data were taken at three nominal pointing positions, which the authors have designated AEGIS-1, AEGIS-2, and AEGIS-3. These observations were all taken in the time period 2007 December 11 to 2009 June 26 using the ACIS-I instrument. The centers of the 3 AEGIS fields correspond fairly closely to those of the EGS-3, EGS-4, and EGS-5 fields of Laird et al. (2009, ApJS, 180, 102). The Rainbow Cosmological Surveys Database (&lt;a href="http://rainbowx.fis.ucm.es/Rainbow_Database/Home.html"&gt;http://rainbowx.fis.ucm.es/Rainbow_Database/Home.html&lt;/a&gt;; see Section 4 of the reference paper for more details) contains many multiwavelength photometric datasets giving information on optical and infrared sources in these fields. The characteristics of these datasets are given in Table 7 of the reference paper. This table was created by the HEASARC in February 2016 based on the &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJS/220/10"&gt;CDS catalog J/ApJS/220/10&lt;/a&gt; files table11.dat, table12.dat, table13.dat, table14.dat and table15.dat.

ACT-America: L2 Weighting Functions for Airborne Lidar Column-avg CO2, Eastern USA

This dataset provides vertical weighting function coefficients of the Level 2 (L2) remotely sensed column-average carbon dioxide (CO2) concentrations measured during airborne campaigns in Summer 2016, Winter 2017, Fall 2017, and Spring 2018 conducted over central and eastern regions of the U.S. for the Atmospheric Carbon and Transport (ACT-America) project. Column-average CO2 concentrations were measured at a 0.1-second frequency during flights of the C-130 Hercules aircraft at altitudes up to 8 km with a Multi-functional Fiber Laser Lidar (MFLL; Harris Corporation). The MFLL is a set of Continuous-Wave (CW) lidar instruments consisting of an intensity-modulated multi-frequency single-beam synchronous-detection Laser Absorption Spectrometer (LAS) operating at 1571 nm for measuring the column amount of CO2 number density and range between the aircraft and the surface or to cloud tops, and surface reflectance and a Pseudo-random Noise (PN) altimeter at 1596 nm for measuring the path length from the aircraft to the scattering surface and/or cloud tops. The MFLL was onboard all ACT-America seasonal campaigns, except Summer 2019. The MFLL-measured column-averaged CO2 values have certain distinct vertical weights on CO2 profiles depending on the meteorological conditions and the wavelengths used at the measurement time and location. This product includes the instrument location at the time of measurement in geographic coordinates and altitude, along with a vector of weighting function values representing conditions along the nadir direction.

Lockman Hole Field XMM-Newton X-Ray Point Source Catalog

This table contains the results of a detailed X-ray spectral analysis of a sample of 123 X-ray sources detected with XMM-Newton in the Lockman Hole field. This is the deepest observation carried out as yet with XMM-Newton with more that 600 ks of good EPIC-pn data.There are spectra with good signal to noise (&gt;500 source counts) for all objects down to 0.2 - 12 keV fluxes of 5 x 10&lt;sup&gt;-15&lt;/sup&gt; erg/cm&lt;sup&gt;2&lt;/sup&gt;/s (the flux limit is 6 x 10&lt;sup&gt;-16&lt;/sup&gt; erg/cm&lt;sup&gt;2&lt;/sup&gt;/s in the 0.5 - 2.0 and 2 - 10 keV bands). At the time of the analysis, the authors had optical spectroscopic identifications for 60% of the sources, 46 being optical type-1 AGN and 28 optical type-2 AGN. Using a single power law model, their sources&#39; average spectral slope hardens at faint 0.5 - 2 keV fluxes but not at faint 2 - 10 keV fluxes. This table was created by the HEASARC in June 2007 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/444/79"&gt;CDS Catalog J/A+A/444/79&lt;/a&gt;, file table8.dat.

ROSAT PSPC Catalog of SMC X-Ray Sources (Haberl et al.)

This is a catalogue of 517 discrete X-ray sources in a 6 degree by 6 degree field covering the Small Magellanic Cloud (SMC). The catalogue was derived from the pointed ROSAT PSPC observations performed between October 1991 and May 1994 and is complementary to the Large Magellanic Cloud (LMC) catalogue published by Haberl &amp; Pietsch (1999, A&amp;AS, 139, 277). The authors followed the same identification scheme and used, among other information, X-ray hardness ratios and spatial extent to classify unknown sources as candidates for active galactic nuclei (AGN), foreground stars, supernova remnants (SNRs), supersoft sources (SSSs) and X-ray binaries. In Table 7 of the paper from which this catalog is taken (Haberl et al. 2000, A&amp;AS, 142, 41), for 158 of these 517 sources a likely source type is given, from which 46 sources are suggested as background AGN (including candidates resulting from a comparison of X-ray and radio images). Nearly all of the X-ray binaries known in the SMC were detected in the ROSAT PSPC observations; most of them with luminosities below 10&lt;sup&gt;36&lt;/sup&gt; erg/s, suggesting that the fraction of high-luminosity X-ray binary systems in the Magellanic Clouds (MCs) is not significantly larger than in our galaxy. This database was created at the HEASARC in June 2000 based on the ADC/&lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+AS/142/41"&gt;CDS Catalog J/A+AS/142/41&lt;/a&gt;, and is derived from Table 2 of the reference.

ABoVE: Passive Microwave-derived Annual Snowpack Main Melt Onset Date Maps, 1988-2023

This dataset provides the annual date of snowpack seasonal beginning melt (i.e., main melt onset date, MMOD) across northwest Canada, Alaska, US, and parts of far eastern Russia at 6.25-km resolution for the period 1988-2023. MMOD was derived from the daily 19V (K-band) and 37V (Ka-band) GHz bands from the Making Earth Science Data Records for Use in Research Environments (MEaSUREs) Calibrated Enhanced-Resolution Passive Microwave (PMW) EASE-Grid Brightness Temperature (Tb) Earth System Data Record (ESDR). The PMW MMOD dataset was validated using the transition date from Freeze Degree Days (FDD) to Thaw Degree Days (TDD) from in situ air temperature observations from 31 SNOw TELemetry network (SNOTEL) stations, and compared to an established Freeze-Thaw ESDR (FT-ESDR) spring onset date record. The resulting MMOD data record is suitable for documenting the spatial-temporal impacts of MMOD variability in ecosystem services, wildlife movements, and hydrologic processes within the ABoVE (Arctic Boreal Vulnerability Experiment) domain. The data from 1988-2016 included a coastal mask removing coastal pixels due to potential water contamination from coarse brightness temperature observations (Dersken et al., 2012). No coastal mask is used for the 2017-2023 data. The full data are included, and data users should be aware that values adjacent to large water bodies can be adversely affected.

ACT-America: L1 DAOD Measurements by Airborne CO2 Lidar, Eastern USA

This dataset provides Level 1 (L1) remotely sensed differential absorption optical depth (DAOD) measurements made through the Multi-Functional Fiber Laser Lidar (MFLL; Harris Corporation) during airborne campaigns in Summer 2016, Winter 2017, Fall 2017, and Spring 2018 conducted over central and eastern regions of the United States for the Atmospheric Carbon and Transport (ACT-America) project. DAOD were measured at 0.1 second frequency during flights of the C-130 Hercules aircraft at altitudes up to 8 km with MFLL. The MFLL is a set of Continuous-Wave (CW) lidar instruments consisting of an intensity modulated multi-frequency single-beam synchronous-detection Laser Absorption Spectrometer (LAS) operating at 1571 nm for measuring the column amount of CO2 number density and range between the aircraft and the surface or to cloud tops, and surface reflectance and a Pseudo-random Noise (PN) altimeter at 1596 nm for measuring the path length from the aircraft to the scattering surface and/or cloud tops. The MFLL was onboard all ACT-America seasonal campaigns, except Summer 2019. Complete aircraft flight information, interpolated to the 0.1 second column CO2 reporting frequency, are included, but not limited to, latitude, longitude, altitude, and attitude. Data users should note that a Level 2 (L2) MFLL data product is available (related dataset) that contains all data variables (plus the column-average CO2) included in this L1 MFLL data product but has undergone additional processing and calibrations and is recommended for most use cases.

NuSTAR Survey of Extended Chandra Deep Field South (ECDF-S) Source Catalog

This table contains the source catalog from the Nuclear Spectroscopic Telescope Array (NuSTAR) survey of the Extended Chandra Deep Field South (hereafter, ECDFS), that is currently the deepest contiguous component of the NuSTAR extragalactic survey program. The survey covers the full ~30&#39; x 30&#39; area of this field to a maximum depth of ~360 ks (~220 ks when corrected for vignetting at 3 - 24 keV), reaching sensitivity limits of ~1.3 x 10&lt;sup&gt;-14&lt;/sup&gt; erg/s/cm&lt;sup&gt;2&lt;/sup&gt; (3 - 8 keV), ~3.4 x 10&lt;sup&gt;-14&lt;/sup&gt; erg/s/cm&lt;sup&gt;2&lt;/sup&gt; (8 - 24 keV), and ~3.0 x 10&lt;sup&gt;-14&lt;/sup&gt; erg/s/cm&lt;sup&gt;2&lt;/sup&gt; (3 - 24 keV). A total of 54 sources are detected over the full field, although five of these are found to lie below our significance threshold once contaminating flux from neighboring (i.e., blended) sources is taken into account. Of the remaining 49 that are significant, 19 are detected in the 8 - 24 keV band. The 8 - 24 to 3 - 8 keV band ratios of the 12 sources that are detected in both bands span the range 0.39 - 1.7, corresponding to a photon index (Gamma) range of about 0.5 - 2.3, with a median photon index of 1.70 +/- 0.52. The redshifts of the 49 sources in the main sample span the range z = 0.21 - 2.7, and their rest-frame 10 - 40 keV luminosities (derived from the observed 8 - 24 keV fluxes) span the range L&lt;sub&gt;10-40keV&lt;/sub&gt; ~ (0.7 - 300) x 10&lt;sup&gt;43&lt;/sup&gt;erg/s, sampling below the &quot;knee&quot; of the X-ray luminosity function out to z ~ 0.8 - 1. Finally, the authors identify one NuSTAR source that has neither a Chandra nor an XMM-Newton counterpart, but that shows evidence of nuclear activity at infrared wavelengths and thus may represent a genuine, new X-ray source detected by NuSTAR in the ECDFS. The NuSTAR ECDFS survey consists of observations from two separate passes. Observations making up the first pass were taken between 2012 September and December, and those making up the second pass were taken roughly six months later, between 2013 March and April. For their cosmological calculations, the authors adopt a Hubble constant H&lt;sub&gt;0&lt;/sub&gt; of 71 km s&lt;sup&gt;-1&lt;/sup&gt; Mpc &lt;sup&gt;-1&lt;/sup&gt;, Omega&lt;sub&gt;M&lt;/sub&gt; of 0.27, and Omega&lt;sub&gt;Lambda&lt;/sub&gt; of 0.73. This table was created by the HEASARC in September 2017 based on the &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJ/808/184"&gt;CDS Catalog J/ApJ/808/184&lt;/a&gt; file catalog.dat.

Radio-Selected Extended Chandra Deep Field South Source Catalog

In order to trace the instantaneous star formation rate (SFR) at high redshift, and thus help in understanding the relation between the different emission mechanisms related to star formation, the authors have combined the recent 4-Ms Chandra X-ray data and the deep Very Large Array radio data in the Extended Chandra Deep Field-South (E-CDF-S) region. They find 268 sources detected both in the X-ray and radio bands. The availability of redshifts for ~ 95% of the sources in their sample allows them to derive reliable luminosity estimates and the intrinsic properties from X-ray analysis for the majority of the objects. The present table lists the X-ray properties and redshifts of these 268 radio-selected sources. In the E-CDF-S area, the authors have two sets of X-ray data obtained with Chandra. The most important is a 4-Ms exposure observation resulting from the co-addition of 54 individual Chandra ACIS-I exposures from 1999 October to 2010 July, with centers spaced within a few arcseconds of RA = 03:32:28.80, Dec = -27:48:23 (J2000). The authors use the data from the new VLA program which provides deep, high-resolution 1.4-GHz imaging across the full E-CDF-S, consisting of a six-pointing mosaic of 240 h spanning 48 d of individual 5-h observations (Miller et al., 2008, ApJS, 179, 114). The E-CDF-S area has been targeted by a large number of spectroscopic surveys. For the X-ray sources, the authors use the spectroscopic redshifts published in Xue et al. (2011, ApJS, 195, 10). This table was created by the HEASARC in May 2013 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/MNRAS/420/2190"&gt;CDS Catalog J/MNRAS/420/2190&lt;/a&gt; files table2.dat and table3.dat.
