Abstract:
This multi-band source catalogue provides aperture photometry in four
near infrared broad-band filters: Y, J, H and Ks for almost 1.4
billion detections. The total coverage of the VHS survey is almost
17000 square degrees in the South Hemisphere.
Description:
Observations were made with the VIRCAM instrument on the ESO-VISTA
telescope between 2009-11-04T12:29:43 and 2017-04-01T14:59:29 in Y, J,
H and Ks filters.

--------------------------------------------------------------------------------
Note (1): This profile classification statistic is a continuously distributed,
Gaussian N(0,1) (i.e. zero mean, unit variance) statistic formed from
the available individual classification statistics by averaging them
and multiplying by N1/2 such that cuts on mergedClassStat result in
completeness being independent of number of frames an object appears
on, but with reliability improving with the number of frames.
Note (2): Class flag from available measurements as follows:
1 = Galaxy (522,436,266 occurrences);
0 = Noise (25,899,664 occurrences);
-1 = Star (631,842,962 occurrences);
-2 = Probable star (180,291,372 occurrences);
-3 = Probable galaxy (13,737,221 occurrences);
Note (3): Magnitudes with errors >100mag have been set to null value by CDS;
their errors have been set to 100mag.
Note (4): Post-processing error quality bit flags assigned to detections in the
archive curation procedure for survey data. From least to most
significant byte in the 4-byte integer attribute byte 0 (bits 0 to 7)
corresponds to information on generally innocuous conditions that are
nonetheless potentially significant as regards the integrity of that
detection; byte 1 (bits 8 to 15) corresponds to warnings; byte 2 (bits
-3 to 23) corresponds to important warnings; and finally byte 3 (bits
0 to 31) corresponds to severe warnings.
See http://horus.roe.ac.uk/vsa/ppErrBits.html
Note (5): If a source is not found to be duplicated in overlap regions, then
priOrSec=0; if a source is duplicated, then priOrSec will be set to
the frameSetID of the source that should be considered the best one to
use out of the set of duplicates.
