II/376 VISTA Variable in the Via Lactea Survey (VVV) DR4.2 (Minniti+, 2023) ================================================================================ VISTA Variables in the Via Lactea Survey (VVV) - ESO Phase 3 - DR4.2 Minniti D., Lucas P., Hempel M., The VVV Science Team. =2023yCat.2376....0M =2012A&A...537A.107S ================================================================================ ADC_Keywords: Surveys ; Infrared sources ; Photometry, infrared Mission_Name: ESO Keywords: Galaxy: bulge - Galaxy: disk - Galaxy: stellar content - stars: abundances - infrared: stars - surveys Abstract: The VVV Survey data delivered to ESO in this "DR4.2" release of the "VVV" Data Collection includes the two-epoch ZYJHKs band-merged tile catalogues that were created by the Wide Field Astronomy Unit (WFAU) at the Royal Observatory, Edinburgh, using single-band catalogues created from the tile images by the Cambridge Astronomical Survey Unit (CASU). These data files were uploaded via the Phase 3 tool to the ESO Archive in July 2020. The data are from ESO programme 179.B-2002, with the VIRCAM instrument, using ZYJHKs filters, with total sky coverage of 540 sq. deg. Description: The ESO public survey VISTA variables in the Via Lactea (VVV) started in 2010. The telescope used to carry out the VVV survey is VISTA (Visible and Infrared Survey Telescope for Astronomy), a 4-m class wide-field telescope with a single instrument, VIRCAM (VISTA InfraRed CAMera), located on its own peak at ESO's Cerro Paranal Observatory in Chile. VIRCAM is equipped with five broad-band filters (Z, Y, J, H, and Ks) and two narrow-band filters centred at 0.98 and 1.18um. The VVV survey uses all five broad-band filters spanning from 0.84 to 2.5um. The VVV survey area consists of 348 tiles, 196 tiles in the bulge and 152 in the disk area. This Phase 3 release contains observations up to 26 September 2015. DR4.2 replaces the previous releases of band-merged tile catalogues in DR2 that were derived from the CASU v1.1 or v1.2 pipelines. DR4.2 provides additional data: the band-merged catalogues now include two separate epochs of contemporaneous JHKs photometry and two separate epochs of contemporaneous ZY photometry.

Classification of variability in this band (VARFLAG) 1801 I1 --- Prim [0/1]? 1=Primary source; 0=secondary source (PRIMARY_SOURCE) -------------------------------------------------------------------------------- Note (1): Class flag as follows: 1 = gal (223,494,864 occurrences) 0 = noise (6,242,984 occurrences) -1 = star (336,856,585 occurrences) -2 = probStar (21,796,600 occurrences) -3 = probGal (2,291,920 occurrences) Note (2): Quality error bit flags assigned during post processing are listed at http://horus.roe.ac.uk/vsa/ppErrBits.html These flags refer to quality issues of varying severity. For each pass-band ten quality issues are implemented as follows, where the corresponding value of the ppErrBit is given in parenthesis. Source is deblended (16), has bad pixel(s) in default aperture (64), has low confidence in default aperture (128), lies within detector #16 region of a tile (4096), is close to saturation (65536), has photometric calibration probably subject to systematic errors (131072), lies within a dither offset of the stacked frame boundary (4194304), lies within the underexposed strip of a tile (8388606), and lies within an underexposed region of a tile due to missing detector (16777216), and corresponds to a bright tile detection, but no detection in pawprints (67108864). To select only sources without quality issues the user can filter on ppErrBits=0, but note that all sources in this catalog have at least ppErrBits=16 due to the dense stellar field, and to include only sources with minor quality issues use ppErrBits<256. -------------------------------------------------------------------------------- History: Catalog downloaded from: http://www.eso.org/qi/catalog/show/345 Description available on: http://www.eso.org/rm/api/v1/public/releaseDescriptions/161 ================================================================================ (End) F.-X.
