ABoVE: Lichen Forage Cover over Fortymile Caribou Range, Alaska and Yukon, 2000-2015

This dataset provides modeled estimates of lichen ground cover at 30 m resolution across the Fortymile study area in interior eastern Alaska, U.S., and the Yukon Territory, Canada, for the nominal year 2015. The mapped lichens are important winter forage for the nine resident caribou (Rangifer tarandus) herds in the region. A random forest modeling approach with vegetation inputs and environmental and spectral predictors was used to estimate lichen cover for 2015. Input data for the model were aggregated from historical in-situ vegetation plots, visual aerial surveys, and recent unmanned aerial system (UAS) imagery to align with 30 m resolution Landsat pixels over the 583,200 km2 study area. The model was also used to estimate lichen cover for the year 2000 by applying the trained model to historical Landsat imagery. An estimate of lichen volume in 2015, based on a published algorithm, is also provided. In addition, site-level presence-absence maps at <1 m resolution and site-level lichen cover maps at both 2 m and 30 resolution are provided. Site-level data were derived from high-resolution RGB imagery collected in summer 2017 from UASs at 22 forested and alpine sites across interior Alaska and western Yukon. Due to the use of two unique UAS imagers at 7 sites, there are 29 data collections across the 22 sites. Each UAS data collection is associated with three data files. These landscape-scale maps could be useful for understanding trends in lichen abundance and distribution, as well as for caribou research, management, and conservation.

AMI Galactic Plane Survey 16-GHz Source Catalog

The Arcminute Microkelvin Imager (AMI) Galactic Plane Survey is a large-area survey of the outer Galactic plane to provide arcminute resolution (approximately 3 arcminutes) images at milli-Jansky (mJy) sensitivity in the centimeter-wave band. This table contains results from the first data release of the survey, consisting of 868 deg&lt;sup&gt;2&lt;/sup&gt; of the Galactic plane, covering the area above 40 degrees Declination (corresponding to 76 to 170 degrees Galactic Longitude) between Galactic Latitudes of -5 to +5 degrees at a central frequency of 15.75 GHz (1.9 cm). The noise level in the survey is &lt;~ 3mJy/beam away from bright sources. This table contains the source catalog of 3503 radio sources detected with peak flux densities at or greater than 5 sigma. In their paper, the authors describe in detail the drift-scan observations which have been used to construct the maps, including the techniques used for observing, mapping and source extraction, and summarize the properties of the finalized data sets. These observations constitute the most sensitive Galactic plane survey of large extent at centimeter-wave frequencies greater than 1.4 GHz. This table was originally ingested by the HEASARC in March 2013 based on the &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/MNRAS/429/3330"&gt;CDS Catalog J/MNRAS/429/3330&lt;/a&gt; file catdr1.dat. It was updated in September 2013 using the latest data file from the CDS, which provided positions with improved precision. This is a service provided by NASA HEASARC .

Australia Telescope ESO Slice Project 1.4-GHz Source Catalog

The Australia Telescope ESO Slice Project (ATESP) survey is a radio survey which was accomplished with the Australia Telescope Compact Array (ATCA) at 1.4 GHz over the region covered by the ESO Slice Project (ESP: Vettolani et al. 1997, A&amp;A, 325, 954) galaxy redshift survey. This 26-degree&lt;sup&gt;2&lt;/sup&gt; region is centered at Declination -40 degrees, and ranges in RA from 22&lt;sup&gt;h&lt;/sup&gt; 30&lt;sup&gt;m&lt;/sup&gt; to 01&lt;sup&gt;h&lt;/sup&gt; 15&lt;sup&gt;m&lt;/sup&gt;. The ATESP survey consisted of 16 radio mosaics with 8 x 14 arcseconds resolution and uniform sensitivity (1 sigma noise level of ~ 79 microJansky) over the whole area of the ESP redshift survey. According to the reference paper, the final 6-sigma ATESP catalog contained 2960 sources down to a detection limit of ~ 0.5 mJy (6 sigma), 1402 of which are sub-mJy sources, and 189 of which are multiple sources (168 doubles, 19 triples and 2 quadruples). This table contains the list of 6-sigma or more sources detected in the ATESP survey. For composite sources with multiple components, the individual components each have entries in this table, and there is also an entry for the entire source. Based on the numbers quoted above, this would imply that there should be (2960 + 2*168 + 3*19 + 4*2) = 3361 entries in this table. The HEASARC notes that there are actually 3370 entries in the CDS version of this table that the present table is based on, 169 of which are doubles, 19 triples and 2 quadruples, implying that this version has 2967 sources, slightly more than the number quoted in the reference paper. This table was created by the HEASARC in November 2012 based on the &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/VIII/63"&gt;CDS Catalog VIII/63&lt;/a&gt; file atesp.dat.

PPM-XL Bright M Dwarfs Catalog

Using the Position and Proper Motion Extended-L (PPMXL) catalog, the authors have used optical and near-infrared color cuts together with a reduced proper motion cut to find bright M dwarfs for future exoplanet transit studies. PPMXL&#39;s low proper-motion uncertainties allow them to probe down to smaller proper motions than previous similar studies. The authors have combined unique objects found with this method to that of previous work to produce 8,479 K &lt; 9th magnitude M dwarfs. Low-resolution spectroscopy was obtained of a sample of the objects found using this selection method to gain statistics on their spectral type and physical properties. Results show a spectral-type range of K7 to M4V. This catalog is the most complete collection of K &lt; 9 M dwarfs currently available and is made available herein. The PPMXL catalog (Roeser et al. 2010) represents a combination of the USNO-B1.0 and Two Micron All-Sky Survey (2MASS) catalogs mapped on to the International Celestial Reference Frame (ICRF), which allows proper motions to be described in a quasi-absolute manner as opposed to relative. PPMXL now provides low uncertainties for both the proper motion and position for many of the objects within the two catalogs. Typical uncertainties for proper motions are 4 - 10 mas/yr. The NIR JHK magnitudes from 2MASS and the optical BVRI magnitudes from USNO-B1.0 also provide very useful color information about the objects and are used during the sample selection process. In this work, the authors classified 4,054 M dwarfs with magnitudes of K &lt; 9 from the PPMXL catalog. By probing down to lower proper motions, this work has produced 1,193 new bright M dwarf candidates that were not included in previous catalogs. By combining these objects with M dwarfs from Lepine &amp; Gaidos (2011, AJ, 142, 138) the authors obtained a final catalog with 8,479 K &lt; 9 late K and M dwarfs suitable for future exoplanet transit studies. This table was created by the HEASARC in February 2015 based on the &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/MNRAS/435/2161"&gt;CDS Catalog J/MNRAS/435/2161&lt;/a&gt; file table3.dat.

ABoVE: LVIS L3 Gridded Vegetation Structure across North America, 2017 and 2019

This dataset provides Level 3 (L3) footprint-level gridded metrics and attributes collected from NASA's Land, Vegetation, and Ice Sensor (LVIS)-Facility instrument for each flightline from 2017 and 2019. In 2017, the LVIS-Facility instrument was flown at a nominal flight altitude of 28,000 ft onboard a Dynamic Aviation Super King Air B200T. In 2019, the LVIS-Facility and LVIS-Classic instruments were flown at a nominal flight altitude of 41,000 feet onboard the NASA Gulfstream V. LVIS data are collected as waveforms over footprints of ~10-m diameter. The L3 data include grids of canopy relative height (RH), complexity, canopy cover (CC), ground elevation, and the number of LVIS footprints available to produce a pixel's estimate.. These 30-m resolution grids describe the vertical column of the vegetation canopy in detail with relative canopy height metrics and are enriched with an additional set of canopy cover estimates at a variety of height thresholds. The LVIS-Facility instrument 2017 and 2019 acquisitions span Arctic, boreal, temperate, and sub-tropical landscapes in support of a variety of Arctic-Boreal Vulnerability Experiment (ABoVE)- and Global Ecosystem Dynamics Investigation (GEDI)-related science. In the ABoVE study domain of arctic and boreal Alaska and Western Canada, some of these acquisitions coincide spatially with legacy small-footprint airborne lidar. Data are included for the ABoVE domain and also for the continental U.S. and central America in support of GEDI calibration and validation. Data files are provided in GeoTIFF format and one geopackage file shows flightlines.

Collinder 69 Cluster XMM-Newton X-Ray Point Source Catalog

This table contains some of the results from the first paper of a series devoted to the Lambda Orionis star-forming region, Orion&#39;s Head, from the X-ray perspective. The final aim of this research is to provide a comprehensive view of this complex region, which includes several distinct associations and dark clouds. The authors aim to uncover the population of the central, young star cluster Collinder 69, and in particular to find those diskless Class III pre-main sequence objects which have not been identified by previous surveys based on near- and mid-infrared searches, and to establish the X-ray luminosity function for the association. The authors have combined two exposures taken with the XMM-Newton satellite with an exhaustive data set of optical, near- and mid-infrared photometry to assess the membership of the X-ray sources based on different color-color and color-magnitude diagrams, as well as other properties, such as effective temperatures, masses and bolometric luminosities derived from spectral energy distribution fitting and comparison with theoretical isochrones. The presence of circumstellar disks is discussed using mid-infrared photometry from the Spitzer Space Telescope. This table contains the XMM-Newton X-ray point source catalog for all sources detected in the EPIC observations of the Collinder 69, East and West Fields (C69E and C69W), respectively, with maximum likelihood (ML) values &gt; 15.0. A companion HEASARC Browse table COLL69OID contains optical and infrared data as well as membership information on counterparts to these X-ray sources. This table was created by the HEASARC in July 2011 based on the electronic versions of Tables 3 and 4 from the reference paper which were obtained from the CDS (their catalog J/A+A/526/A21 files table3.dat and table4.dat).

Aquarius CAP Level 3 Sea Surface Salinity Standard Mapped Image Monthly Data V5.0

Version 5.0 Aquarius CAP Level 3 products are the fourth release of the AQUARIUS/SAC-D mapped salinity and wind speed data based on the Combined Active Passive (CAP) algorithm. CAP Level 3 standard mapped image products contain gridded 1 degree spatial resolution salinity and wind speed data averaged over 7 day and monthly time scales. This particular dataset is the monthly sea surface salinity (SSS) V5.0 Aquarius CAP product. CAP is a P.I. produced dataset developed and provided by JPL. The CAP algorithm utilizes data from both the onboard radiometer and scatterometer to simultaneously retrieve salinity, wind speed and direction by minimizing the sum of squared differences between model and observations. The main improvements in CAP V5.0 relative to the previous version include: updates to the Geophysical Model Functions to 4th order harmonics with the inclusion of sea surface temperature (SST) and stability at air-sea interface effects; use of the Canadian Meteorological Center (CMC) SST product as the new source ancillary sea surface temperature data in place of NOAA OI SST. The Aquarius instrument is onboard the AQUARIUS/SAC-D satellite, a collaborative effort between NASA and the Argentinian Space Agency Comision Nacional de Actividades Espaciales (CONAE). The instrument consists of three radiometers in push broom alignment at incidence angles of 29, 38, and 46 degrees incidence angles relative to the shadow side of the orbit. Footprints for the beams are: 76 km (along-track) x 94 km (cross-track), 84 km x 120 km and 96km x 156 km, yielding a total cross-track swath of 370 km. The radiometers measure brightness temperature at 1.413 GHz in their respective horizontal and vertical polarizations (TH and TV). A scatterometer operating at 1.26 GHz measures ocean backscatter in each footprint that is used for surface roughness corrections in the estimation of salinity. The scatterometer has an approximate 390km swath.

MAGELLAN SOLAR CORONA                                         AND FARADAY ROTATION V1.0

This data set contains raw and partially processed data from      observations of Magellan radio transmissions while the signal      was passing through the solar corona.  Scintillations on the      signal can be related to structure and motion of the coronal      material [WOO1993]; polarization of the signal can be used to      infer magnetic field within the plasma.      Data were acquired using stations of the NASA Deep Space Network      (DSN).  The Magellan spacecraft transmitted signals that were      100 percent linearly polarized at 13 cm and right-elliptically      polarized at 3.6 cm.  During summer 1992, when Magellan was in      solar superior conjunction, the spacecraft came within 0.6 solar      radii of the Sun's center when viewed from Earth.

Hamburg/RASS Catalog: X-Ray Sources

This table is a representation of part of the Hamburg/ROSAT All-Sky Survey (RASS) Catalog (HRC) of optical identifications of X-ray sources at high-galactic latitude, namely the list of X-ray sources. (The list of proposed and possible optical counterparts is given in the linked Browse table HRASSOPTID). The HRC includes all X-ray sources from the ROSAT Bright Source Catalog (RASS-BSC) with galactic latitude |b| &gt;= 30 degrees and declination Dec &gt;= 0 degrees. In this part of the sky covering ~10,000 square degrees, the RASS-BSC contains 5341 X-ray sources. For the optical identification, the HRC authors used blue Schmidt prism and direct plates taken for the northern hemisphere Hamburg Quasar Survey (HQS) which are now available in digitized form. The limiting magnitudes are 18.5 and 20, respectively. For 82% of the selected RASS-BSC, an identification could be given. For the rest, either no counterpart was visible in the error circle, or a plausible identification was not possible. With ~42%, AGN represent the largest group of X-ray emitters, ~31% have a stellar counterpart, whereas galaxies and cluster of galaxies comprise only ~4% and ~5%, respectively. In ~3% of the RASS-BSC sources, no object was visible on the blue direct plates within 40&quot; around the X-ray source position. The catalog has been used as a source for the selection of (nearly) complete samples of the various classes of X-ray emitters. This table was produced by the HEASARC in February 2005 based on the CDS Catalog table J/A+A/406/353/x-ray.dat. This is a service provided by NASA HEASARC .

Chandra Archive Of Galaxies Ultraluminous X-Ray Source Catalog

One hundred fifty-five (the abstract in the paper erroneously states the number to be 154) discrete, non-nuclear, ultraluminous X-ray (ULX) sources, with spectroscopically determined intrinsic X-ray luminosities greater than 10&lt;sup&gt;39&lt;/sup&gt; erg/s, have been identified in 82 galaxies that were observed with Chandra&#39;s Advanced CCD Imaging Spectrometer (ACIS). Positions, X-ray luminosities, and spectral and timing characteristics of these ULXs are contained in this table. Eighty-three percent of ULX candidates have spectra that can be described as absorbed power laws with mean index Gamma = 1.74 and column density N&lt;sub&gt;H&lt;/sub&gt; = 2.24 x 10&lt;sup&gt;21&lt;/sup&gt; atoms cm&lt;sup&gt;-2&lt;/sup&gt;, or ~5 times the average Galactic column. About 20% of the ULXs have much steeper indices indicative of a soft, and likely thermal, spectrum. The locations of ULXs in their host galaxies are strongly peaked toward their galaxy centers. The deprojected radial distribution of the ULX candidates is somewhat steeper than an exponential disk, indistinguishable from that of the weaker sources. About 5%-15% of ULX candidates are variable during the Chandra observations (which average 39.5 ks). Comparison of the cumulative X-ray luminosity functions of the ULXs to Chandra Deep Field results suggests ~25% of the sources may be background objects, including 14% of the ULX candidates in the sample of spiral galaxies and 44% of those in elliptical galaxies, implying the elliptical galaxy ULX population is severely compromised by background active galactic nuclei. Correlations with host galaxy properties confirm the number and total X-ray luminosity of the ULXs are associated with recent star formation and with galaxy merging and interactions. The preponderance of ULXs in star-forming galaxies as well as their similarities to less-luminous sources suggest they originate in a young but short-lived population such as the high-mass X-ray binaries, with a smaller contribution (based on spectral slope) from recent supernovae. The number of ULXs in elliptical galaxies scales with host galaxy mass and can be explained most simply as the high-luminosity end of the low-mass X-ray binary population. This table was created by the HEASARC in March 2007 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJS/154/519"&gt;CDS catalog J/ApJS/154/519&lt;/a&gt; file table2.dat.
