1. AllWISE Atlas (L3a) Coadd Images
ID:

Title:
AllWISE Atlas (L3a) Coadd Images
Short Name:
AllWISE L3a
Date:

Publisher:
NASA/IPAC Infrared Science Archive
Description:
The AllWISE program builds upon the work of the successful Wide-field Infrared Survey Explorer mission (WISE; Wright et al. 2010) by combining data from the WISE cryogenic and NEOWISE (Mainzer et al. 2011 ApJ, 731, 53) post-cryogenic survey phases to form the most comprehensive view of the full mid-infrared sky currently available. By combining the data from two complete sky coverage epochs using an advanced data processing system, AllWISE has generated new products that have enhanced photometric sensitivity and accuracy, and improved astrometric precision compared to the 2012 WISE All-Sky Data Release. Exploiting the 6 to 12 month baseline between the WISE sky coverage epochs enables AllWISE to measure source motions for the first time, and to compute improved flux variability statistics. The AllWISE Images Atlas is comprised of 18,240 4-band calibrated 1.56°x1.56° FITS images, depth-of-coverage and noise maps, and image metadata produced by coadding nearly 7.9 million Single-exposure images from all survey phases.

Title:
Arecibo Legacy Fast ALFA Survey
Short Name:
ALFALFA
Date:

Publisher:
Cornell University
Description:
The Arecibo Legacy Fast ALFA extragalactic HI survey uses the Arecibo multibeam receiver to survey 7000 square degrees of high galactic latitude sky. Utilizing the high sensitivity of Arecibo, the survey will detect over 20000 HI sources in the local universe. The survey products include catalogs with extracted measurements and HI parameters, as well as integrated HI spectral profiles. The survey is currently served by NED.
3. Deep Near-Infrared Survey of the Southern Sky (DENIS) Catalog
ID:

Title:
Deep Near-Infrared Survey of the Southern Sky (DENIS) Catalog
Short Name:
DENIS
Date:
04 Dec 2017 21:44:08
Publisher:
NASA/IPAC Infrared Science Archive
Description:
This data release, from 2005 September, consists of 355,220,325 point sources detected by DENIS. The release contains 3662 strips, each of which is 30 degrees long in Declination and 12 arcmin wide in Right Ascension (with an overlap of 2 arcminutes between consecutive strips), and covers approximately 16,700 square degrees of the southern sky. The northernmost declination covered is ~+02d07m and the southernmost is ~-87d37m. Multiple detections of single point sources have been merged in image overlaps within individual strips, but sources can have multiple detections in overlapping strips. DENIS observations began at the end of 1995 and were completed on 09 September 2001. The survey was conducted simultaneously in three bands: one optical band (Gunn-i at 0.82um, hereafter referred to as "I") and two near-infrared bands (J at 1.25um and Ks at 2.15um), with limiting magnitudes of 18.5 mag, 16.5 mag, and 14.0 mag and saturation magnitudes of 9.8 mag, 7.5 mag, and 6 mag at I, J, and Ks, respectively. Documentation at CDS states that the astrometric accuracy of a typical point source is better than 1 arcsec and photometric accuracy is better than 0.1 mag, although the range of SNR over which these apply is not specified. DENIS was conducted by a European consortium using the 1m telescope at the European Southern Observatory in La Silla, Chile.

7. 2MASS 6X Extended Source Working Database Table

2MASS 6X Extended Source Working Database Table
Short Name:
2MASS 6XXSWDB
Date:

Publisher:
NASA/IPAC Infrared Science Archive
Description:
During the final months of 2MASS observatory operations, a campaign of targeted "long exposure" observations was carried out during times when no previously unscanned parts of the sky were available for the main survey. These observations used the same freeze-frame scanning technique employed for the survey, but with READ2-READ1 exposures six times longer than was used for normal survey observations (hence they are referred to as "6x" observations). The 2MASS 6x measurements were intended to probe ~1 magnitude deeper than the main survey in unconfused regions. Approximately 590 deg2 of sky distributed in 30 targeted regions were scanned at least once using the long exposures. Most of this area is concentrated in two large, comprehensive surveys of the Large and Small Magellanic Clouds, 383 deg2 and 127 deg2, respectively. Twenty-eight additional smaller fields were mapped in the 6x mode from both observatories, covering targets that include the Pleiades open cluster, galactic star formation complexes, M31, nearby galaxy clusters and the Lockman Hole. Data processing produced a 6x Image Atlas and 6x point and extended source Working Databases (6x-PSWDB and 6x-XSWDB), analogous to those from the main survey. "Catalogs" of point and extended source detections (6x-PSC and 6x-XSC) that represent uniform, higher reliability single-epoch snapshots of the near infrared sky were drawn from the 6x WDBs using SNR and quality criteria similar to those used to construct the All-Sky Release PSC and XSC (A3.6.c). The 6x-PSC and 6x-XSC have not received the same level of scrutiny and validation as the 2MASS All-Sky PSC and XSC, though. Unlike the All-Sky Release Catalogs, the 6x Catalogs are not released as separate tables. The 6x Point and Extended Source Catalogs are instead integrated into the respective 6x Point and Extended Source WDBs. Sources comprising the Catalogs are denoted in the WDBs with the cat flag, and have cat="1".

The merged source tables contain the mean positions magnitudes and uncertainties for sources detected multiple times in each of the 2MASS data sets. The merging was carried out using an autocorrelation of the respective databases to identify groups of extractions that are positionally associated with each other, all lying within a 1.5" radius circular region. A number of confirmation statistics are also provided in the tables that can be used to test for source motion and/or variability, and the general quality of the merge.
