Aquarius Official Release Level 3 Sea Surface Density Standard Mapped Image Monthly Climatology Data V5.0

Aquarius Level 3 sea surface density standard mapped image data contains gridded 1 degree spatial resolution derived density averaged over daily, 7 day, monthly, and seasonal time scales. This particular data set is the monthly climatology, sea surface density 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. Surface density estimates are based on TEOS-10 and derived using retrieved salinity from Aquarius and collocated ancillary SST (Reynolds OI 0.25 degree 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.

Hipparcos New Astrometric Catalog

A new reduction of the astrometric data as produced by the Hipparcos mission has been published, claiming accuracies for nearly all stars brighter than Hipparcos magnitude H_p = 8 to be better, by up to a factor 4, than in the original catalog. The new Hipparcos astrometric catalog has been checked for the quality of the data and the consistency of the formal errors as well as the possible presence of error correlations. The differences with the earlier publication of the Hipparcos Catalog are explained in the reference paper. The internal errors are followed through the reduction process, and the external errors are investigated on the basis of a comparison with radio observations of a small selection of stars, and the distribution of negative parallaxes. Error correlation levels are investigated and the reduction by more than a factor 10 as obtained in the new catalog is explained. The formal errors on the parallaxes for the new catalog are confirmed. The presence of a small amount of additional noise, though unlikely, cannot be ruled out. The new reduction of the Hipparcos astrometric data provides an improvement by a factor 2.2 in the total weight compared to the Hipparcos catalog published in 1997, and, according to the author, provides much improved data for a wide range of studies on stellar luminosities and local galactic kinematics. Note that this catalog version is slightly different from the one published in the book, as an error that sometimes affected the goodness of fit value for the solution was corrected. The first version of these data archived at the CDS (between June and 15 September 2008) also contained errors which were corrected after this date. This table was created by the HEASARC in August 2009 based on the &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/I/311"&gt;CDS Catalog I/311&lt;/a&gt; file hip2.dat, &quot;the Astrometric Catalogue&quot;.

Catalog of High-Mass X-Ray Binaries in the Galaxy (4th Ed.)

This table contains the 4th edition of the Catalog of High-Mass X-Ray Binaries (HMXBs) in the Galaxy. The catalog contains source name(s), coordinates, finding charts, X-ray luminosities, system parameters, and stellar parameters of the components and other characteristic properties for 114 HMXBs, together with a comprehensive selection of the relevant literature. The aim of this catalog is to provide some basic information on the X-ray sources and their counterparts in other wavelength ranges (gamma-rays, UV, optical, IR, radio). About 60% of the high-mass X-ray binary candidates are known or suspected Be/X-ray binaries, while 32% are supergiant/X-ray binaries. Some sources, however, are only tentatively identified as high-mass X-ray binaries on the basis of their X-ray properties similar to the known high-mass X-ray binaries. Further identification in other wavelength bands is needed to finally determine the nature of these sources. In cases where there is some doubt about the high-mass nature of the X-ray binary this is noted. Literature published before 1 October 2005 has, as far as possible, been taken into account. Information on the numbers used to code references is available at the URL &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/455/1165/refs.dat"&gt;https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/455/1165/refs.dat&lt;/a&gt; Individual notes on each HMXB are available at the URL &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/455/1165/notes.dat"&gt;https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/455/1165/notes.dat&lt;/a&gt; This database was first created by the HEASARC in January 2001, based on the 2000 version of this catalog. It was updated to the 4th edition in September 2006, based on the &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/A+A/455/1165"&gt;CDS catalog J/A+A/455/1165&lt;/a&gt;.

Pan-STARRS DR1 "Best" Catalog ConeSearch

Pan-STARRS is a system for wide-field astronomical imaging developed and operated by the Institute for Astronomy at the University of Hawaii. Pan-STARRS1 (PS1) is the first part of Pan-STARRS to be completed and is the basis for Data Release 1 (DR1).  The PS1 survey used a 1.8 meter telescope and its 1.4 Gigapixel camera (GPC1; see PS1 GPC1 camera) to image the sky in five broadband  filters (g, r, i, z, y). The PS1 Science Consortium funded the operation of the Pan-STARRS1 telescope, situated at Haleakala Observatories near the summit of Haleakala in Hawaii, for the purposes of astronomical research. The PS1 consortium is made up of astronomers and engineers from 14 institutions from six countries.\n\nThe Pan-STARRS Data Release 1 Object Catalog "Best" filtered exists in the MAST holdings and is thus available through a cone search. The filtered data is a ~2billion row subset based on an object having more than 2 detections.\nAll available catalogs are listed at http://archive.stsci.edu/vo/mast_services.html.

ER2 EARTH AVIRIS CALIBRATED REDUCED DATA RECORD IMAGE V1.0

The Airborne Visible and Infared Imaging Spectrometer (AVIRIS) data are divided into 10x10 square kilometer scenes for purposes of standard product generation. More than 40 scenes were generated during GRSFE, more than 20 of which are included on the CD-ROMs, covering a variety of surfaces. Lunar Crater was covered several times in one day (under clear atmospheric conditions) in order to evaluate atmospheric scattering and absorption removal algorithms and to explore extraction of roughness information using variable incidence angle AVIRIS data. The AVIRIS multi-temporal data were acquired at the same time that ground-based, multi-spectral measurements of atmospheric optical depth, and sky radiance at varying scattering angles were acquired, along with surface bidirectional reflectance data. Accurate wavelength calibration of AVIRIS was performed by JPL using laboratory measurements acquired before and after the AVIRIS flights. An additional check on the wavelength calibration can be made by comparing the positions of known atmospheric absorption features to their locations in actual AVIRIS data.

OCRA-p Survey of a Subset of CRATES Sources

Knowledge of the population of radio sources in the range ~ 2-200 GHz range is important for understanding their effects on measurements of the cosmic microwave background power spectrum. This table contains measurements of the 30-GHz flux densities of 605 radio sources from the Combined Radio All-sky Targeted Eight-GHz Survey (CRATES), which have been made with the One Centimetre Receiver Array-prototype (OCRA-p) on the Torun 32-m telescope. The flux densities of sources that were also observed by Wilkinson Microwave Anisotropy Probe (WMAP) and previous OCRA surveys are in broad agreement with those reported here, however a number of sources display intrinsic variability. The authors find a good correlation between the 30 GHz and Fermi gamma-ray flux densities for sources in common. In their paper, they examine the radio spectra of all observed sources and report a number of gigahertz-peaked and inverted spectrum sources. These measurements will be useful for comparison to those from the Low Frequency Instrument of the Planck satellite, which will make some of its most sensitive observations in the region covered here. The selection criteria for the subsample of CRATES sources observed by the OCRA-p are given in Section 2 of the reference paper (q.v.). Plots of the measurements of each source over time and the aggregated source spectra between 26 MHz and 150 GHz are available online at the authors&#39; web site: &lt;a href="http://www.jb.man.ac.uk/research/ocra/crates/"&gt;http://www.jb.man.ac.uk/research/ocra/crates/&lt;/a&gt;. This table was created by the HEASARC in May 2011 based on an electronic version of Table 3 of the reference paper which was obtained from the authors&#39; web site &lt;a href="http://www.jb.man.ac.uk/research/ocra/crates/"&gt;http://www.jb.man.ac.uk/research/ocra/crates/&lt;/a&gt;. Notice that the version here is the 10-Jan-2011 version which contains corrections to the 30-GHz flux densities and their errors of ~ 1% in the calibration and the application of the gain-elevation curve.

HerMES 500 micron StarFinder Catalog

The Herschel Multi-tiered Extragalactic Survey (HerMES) is a legacy programme (KPGT_soliver1) designed to map a set of nested fields totalling 380 sq. deg. Fields range in size from 0.01 to 20 sq. deg., using SPIRE at 250, 350 and 500 microns. These bands cover the peak of the redshifted thermal spectral energy distribution from interstellar dust and thus capture the reprocessed optical and ultraviolet radiation from star formation that has been absorbed by dust, and are critical for forming a complete multiwavelength understanding of galaxy formation and evolution.

X-Ray Binaries Catalog

XRBCAT is a catalog of X-ray binaries, based on the van Paradijs (1996) compilation, and updated by Nick White to include all the new (mostly transient) systems discovered since then up until the last update (see below). The information in XRBCAT is basic and does not attempt to be complete. It includes the name of the source, the position, the pulse or orbital period (if one is known), the object class, a flux (a maximum and, if available, a minimum), and an optical V magnitude (if available). To reference XRBCAT, please use the following acknowledgment: &quot;This paper utilized the HEASARC XRBCAT X-ray Binary catalog&quot;. Since it is a very time consuming task to keep track of all the new sources and discoveries, there may be incomplete or missing sources. This catalog was last updated on April 22, 1998.

Fermi LAT Gamma-Ray Blazar Classification Catalog

This database table contains a catalog of classifications for blazar candidates of uncertain type (BCU) detected by the Fermi Large Area Telescope gamma-ray instrument. These classifications have been determined by an Artificial Neural Network machine learning method. The aim of the authors&#39; study was to develop an optimized version of this Artificial Neural Network machine learning method for classifying these blazar candidates. The final result of this study increased the classification performance by about 80% with respect to the method previously used for the classification of uncertain blazars in Chiaro et al. (&lt;a href="https://ui.adsabs.harvard.edu/abs/2016MNRAS.462.3180C"&gt;2016MNRAS.462.3180C&lt;/a&gt;, &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/MNRAS/462/3180/"&gt;CDS Cat. J/MNRAS/462/3180&lt;/a&gt;), leaving only 15 unclassified blazars out of 573 blazar candidates of uncertain type listed in the Fermi LAT 4-Year Source Catalog. Looking beyond the gamma-ray features of blazars, interesting information can be obtained from a multiwavelength study of the sources and particularly from X-ray and radio flux. In this study the authors tested the possibility to use those two parameters to improve the performance of the network. They did not consider any optical spectroscopy data because, when considering uncertain sources, optical spectra are very often not available or not sufficiently descriptive of the nature of the source. The gamma-ray flux was obtained by adding five time-integrated fluxes in five bands (0.1-0.3, 0.3-1, 1-3, 3-10, 10-100 GeV) from the &lt;a href="/W3Browse/fermi/fermi3fgl.html"&gt;3FGL Catalog&lt;/a&gt; (Acero et al. &lt;a href="https://ui.adsabs.harvard.edu/abs/2015ApJS..218...23A"&gt;2015ApJS..218...23A&lt;/a&gt;, &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJS/218/23/"&gt;CDS Cat. J/ApJS/218/23&lt;/a&gt;). Radio and X-ray data were obtained from the Fermi LAT 4-Year AGN Catalog 3LAC (Ackermann et al. &lt;a href="https://ui.adsabs.harvard.edu/abs/2015ApJ...810...14A"&gt;2015ApJ...810...14A&lt;/a&gt;, &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/ApJ/810/14/"&gt;CDS Cat. J/ApJ/810/14&lt;/a&gt;). Radio fluxes used were measured at frequencies of 1.4 and 0.8 GHz; the X-ray fluxes were measured in the 0.1-2.4keV range. The complete list of 567 classified BCUs is presented in this table in which sources are ordered by increasing likelihood of a source being a BL Lac. This database table was ingested by the HEASARC in May 2023 based upon the &lt;a href="https://cdsarc.cds.unistra.fr/ftp/cats/J/MNRAS/490/4770"&gt;CDS Catalog J/MNRAS/490/4770&lt;/a&gt; file table1.dat.
