Abstract:
The first Galactic and extragalactic results from the VISTA Hemisphere
Survey (VHS) are presented. The aim of the VHS is to carry out a
near-infrared survey which, when combined with other VISTA public
surveys, will result in coverage of the whole southern celestial
hemisphere (∼20000deg2) to a depth 30 times fainter than the Two
Micron All Sky Survey in at least two wavebands (J and Ks). The VHS
vision includes a deep optical survey over the same area and this is
now being realised with the VST surveys and the Dark Energy Survey,
which has recently started. A summary of the survey progress is
presented, with some follow-up results on low-mass stars and
high-redshift quasars.
Description:
Observations were made with the VIRCAM instrument on the ESO-VISTA
telescope between 2009 November and 2013 October in Y, J, H and Ks
filters.
Acknowledging the VHS in publications:
Please include the following acknowledgment in any published material
that makes use of the VHS products: Based on observations made with
ESO Telescopes at the La Silla or Paranal Observatories under
programme ID 179.A-2010

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;
0 = Noise;
-1 = Star;
-2 = Probable star;
-3 = Probable galaxy;
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.
