Aquarius Official Release Level 3 Sea Surface Salinity Standard Mapped Image Ascending Annual Data V5.0

Aquarius Level 3 sea surface salinity (SSS) standard mapped image data contains gridded 1 degree spatial resolution SSS averaged over daily, 7 day, monthly, and seasonal time scales. This particular data set is the Annual, Ascending sea surface salinity product for version 5.0 of the Aquarius data set, which is the official end of mission public data release from the AQUARIUS/SAC-D mission. Only retrieved values for Ascending passes have been used to create this product. 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.

COSMOS Zamojski Morphology Catalog

COSMOS is an astronomical survey designed to probe the formation and evolution of galaxies as a function of cosmic time (redshift) and large scale structural environment. The survey covers a 2 square degree equatorial field with imaging by most of the major space-based telescopes (Hubble, Spitzer, GALEX, XMM, Chandra) and a number of large ground based telescopes (Subaru, VLA, ESO-VLT, UKIRT, NOAO, CFHT, and others). Over 2 million galaxies are detected, spanning 75% of the age of the universe.\n\nObjects in this catalog were selected from the 2005 release of the ground-based photometry catalog, with the criterion that their I-band (auto) magnitude had to be <= 23. The IDs, ra and dec provided in this catalog correspond to those of that 2005 release.

INTEGRAL ISGRI 4-Year Source Catalog

In its first 4 years of observing the sky above 20 keV, the INTEGRAL Soft Gamma-ray Imager (ISGRI) detected ~ 500 sources, around half of which were new or unknown at these energies. Follow-up observations at other wavelengths revealed that some of these sources feature unusually large column densities, long pulsations, and other interesting characteristics. The authors investigated where new and previously-known sources detected by ISGRI fit in the parameter space of high-energy objects, and they used the parameters to test correlations expected from theoretical predictions. For example, the influence of the local absorbing matter on periodic modulations was studied for Galactic High-Mass X-ray Binaries (HMXBs) with OB supergiant and Be companions. In their paper, they examined the spatial distribution of different types of sources in the Milky Way, using various projections of the Galactic plane, in order to highlight signatures of stellar evolution and to speculate on the origin of the group of sources whose classifications were still uncertain. This table contains all 499 sources detected by ISGRI listed in the reference paper, with the exception of the source &#39;PSR B1841-04&#39; which was removed from the electronic version of the table by the CDS, after discussion with the author. The table contains the most precise coordinates and error radii available in the literature. Classifications are provided for all sources. When available, the published photoelectric absorption in the X-rays, distances/redshifts, and pulsation and orbital periods are also listed. This table was created by the HEASARC in April 2011 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/467/585"&gt;CDS catalog J/A+A/467/585&lt;/a&gt; file table1.dat.

LALA Bootes Field Chandra X-Ray Point Source Catalog

This table contains the results of an analysis of a deep, 172 ks Chandra observation of the Large Area Lyman Alpha survey (LALA) Bootes field which was obtained with the Advanced CCD Imaging Spectrometer (ACIS-I) on board the Chandra X-Ray Observatory. This is one of the deepest Chandra images of the extragalactic sky, with only the 2 Ms Chandra Deep Field North (CDF-N) and the 1 Ms Chandra Deep Field South (CDF-S) observations being substantially deeper. In this table, the X-ray source catalog obtained from this image is presented, along with some results from an analysis of the X-ray source counts and optical identifications. The X-ray image is composed of two individual observations obtained in 2002 and reaches 0.5 - 2.0 and 2.0 - 10.0 keV flux limits of 1.5 x 10&lt;sup&gt;-16&lt;/sup&gt; and 1.0 x 10&lt;sup&gt;-15&lt;/sup&gt; ergs/cm&lt;sup&gt;2&lt;/sup&gt;/s, respectively, for point sources near the aim point. A total of 168 X-ray sources were detected: 160 in the 0.5 - 7.0 keV band, 132 in the 0.5 - 2.0 keV band, and 111 in the 2.0 - 7.0 keV band. Since X-ray source number 122 has two possible optical counterparts, it is listed twice, once for each counterpart, and the total number of entries in this table is this 169. The primary optical data are R-band imaging from the NOAO Deep Wide-Field Survey (NDWFS), with a limiting magnitude of R = 25.7 magnitudes, (Vega, 3-sigma detection level, and a 4&quot; diameter aperture). Optical counterparts within 1.5&quot; or the 3-sigma X-ray positional uncertainties, whichever was larger, were detected above this level in the R band for 144 of the 168 X-ray sources. At least 90% of the optical counterparts should be the correct matches, and, at worst, there might be ~14 false matches.

Chamaeleon I North Cloud Chandra X-Ray Point Source Catalog

This table contains the Chamaeleon (Cha) I North Cloud Chandra X-Ray point source catalog. Sensitive X-ray imaging surveys provide a new and effective tool to establish the census of pre-main-sequence (PMS) stars in nearby young stellar clusters. A deep Chandra X-Ray Observatory (CXO) observation of PMS stars in the Chamaeleon I North cloud achieved a limiting total-band X-ray luminosity of log L&lt;sub&gt;t&lt;/sub&gt; ~ 10&lt;sup&gt;27&lt;/sup&gt; ergs/s (0.5 - 8 keV band) in a 0.8 x 0.8 pc&lt;sup&gt;2&lt;/sup&gt; region. Of the 107 X-ray sources, 37 are associated with Galactic stars, of which 27 are previously recognized cloud members. These include 3 PMS brown dwarfs: the protostellar brown dwarf ISO 192 has a particularly high level of magnetic activity. Follow-up optical photometry and spectroscopy establish that 9-10 of the Chandra sources are probably magnetically active background stars. No new X-ray-discovered stars were confidently found despite the high sensitivity of the Chandra observation. From these findings, the authors argue that the sample of 27 PMS cloud members in the Chandra field is uncontaminated and complete down to K = 12 or a stellar mass of about 0.1 solar masses. A 16&#39;x 16&#39; region of the Cha I North cloud was observed with the imaging array of the Advanced CCD Imaging Spectrometer (ACIS-I) detector on board the Chandra X-Ray Observatory. The observation took place on 2001 July 2.25-3.04 UT with the detector aimpoint set at 11 10 00.0, -76 35 00 (J2000.0 RA and Declination). The effective exposure was 66.3 ksec. The authors also obtained VI-band CCD images of most of the ACIS field with the 1m telescope and CCD detector at the South African Astronomical Observatory (SAAO) during 2002 February. This table was created by the HEASARC in February 2007 based on &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJ/614/267"&gt;CDS catalog J/ApJ/614/267&lt;/a&gt; files table1.dat, table2.dat and table3.dat.

M 33 Chandra X-Ray Point Source Catalog

This database table contains a source list for three Chandra observations of the Local Group galaxy M 33. The observations were centered on the nucleus and on the star-forming region NGC 604. A total of 261 sources were detected in an area of about 0.2 square degrees down to a flux limit of 3 x 10&lt;sup&gt;-16&lt;/sup&gt; erg/s/cm&lt;sup&gt;2&lt;/sup&gt;, which corresponds to a luminosity of ~2 x 10&lt;sup&gt;34&lt;/sup&gt; erg/s at a distance of 840 kpc. The luminosity functions of the X-ray sources observed in M 33 have been constructed and are consistent with those of other star-forming galaxies, taking into account background contamination. In addition, the combination of X-ray color analysis and the existence of &quot;blue&quot; optical counterparts strongly indicates that the X-ray point source population in M 33 consists of young objects. Above 3 x 10&lt;sup&gt;35&lt;/sup&gt; erg/s, there are few X-ray sources in the locus of the X-ray hardness ratio diagram that is generally populated by low-mass X-ray binaries. Notice that each of the 261 X-ray sources in the source list has 3 entries in this table, one for each separate Chandra observation, making a total of 783 entries. The Chandra datasets from which this source list was compiled are available by &lt;a href="/db-perl/W3Browse/w3query.pl?tablehead=name%3Dheasarc_chanmaster&sortvar=obsid&bparam_obsid=786%3B+1730%3B+2023"&gt;querying CHANMASTER for obsids 786, 1730, and 2023&lt;/a&gt;.

MRO CRISM TARGETED EMPIRICAL RECORD V1.0

This volume contains the CRISM Targeted Empirical Record (TER) archive, a collection of multiband image cubes derived from targeted (gimbaled) observations of Mars' surface acquired by the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument on the Mars Reconnaissance Orbiter (MRO) spacecraft. Post-processing attempts to represent the spectrum the instrument would have measured looking at the surface of Mars at a standard illumination geometry, in the absence of atmospheric gases, with aerosol scattering normalized to that at the geometry within the observation that is closest to nadir, in the absence of instrument artifacts. A series of value added products represent spatial variability in signatures of minerals of interest. The data are still in sensor space, allowing map projection using terrain models of the Martian surface that are of better accuracy or spatial resolution than was used to generate the companion Map-projected Targeted Reduced Data Record (MTR) archive.
