Note : this is the description file of the original catalog. This HTML page corresponds well to the original description, but some minor changes in the format may have been introduced in the FITS output files in order to allow for arithmetic operations on quantities such as coordinates and times. h:m:s and d:m:s units are normally converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the units; the value given in the HTML files supersedes the value indicated in the ReadMe file for this catalogue.

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.
