cds-question@unistra.frsurveysgalaxy-planesmilky-way-galaxyinfrared-photometryThe Vista Variables in the Via Lactea (VVV) survey has performed a multi-epoch near-infrared imaging of the inner Galactic plane. High-fidelity photometric catalogs are needed to utilize the data. We aim at producing a deep, point-spread-function (PSF) photometric catalog for the VVV survey J, H, and Ks band data. Specifically, we aim at taking advantage of all the epochs of the survey to reach high limiting magnitudes. We develop an automatic PSF-fitting pipeline based on the DaoPHOT algorithm and perform photometry on the stacked VVV images in J, H, and Ks bands. We present a PSF photometric catalog in the Vega system that contains about 926 million sources in the J, H, and Ks filters. About 10% of the sources are flagged as possible spurious detections. The 5 sigma limiting magnitudes of the sources with high reliability are about 20.8, 19.5, and 18.7mag in the J, H, and Ks band, respectively, depending on the local crowding condition. Our photometric catalog reaches on average about one magnitude deeper than the previously released PSF DoPHOT photometric catalog. It also includes less spurious detections. There are significant differences in the brightnesses of faint sources between our catalog and the previously released one. The likely origin of these differences is in the different photometric algorithms that are utilized; it is not straightforward to assess which catalog is more accurate in which situations. Our new catalog is beneficial especially for science goals that require high limiting magnitudes; our catalog reaches such in fields that have a relatively uniform source number density. Overall, the limiting magnitudes and completeness are different in the fields with different crowding conditions.2019A&A...632A..85Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/632/A85CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://horus.roe.ac.uk/vsa : VSA - VISTA Science Archive Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/632/A85https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/632/A85http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/632/A85https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/632/A85https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/632/A85http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/632/A85GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/632/A85/list (List of released tables (FITS and ascii formats))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/632/A85/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/632/A85/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/632/A85/list?GETtext/xml+votable180.050000true271.0800171-41.7236290.0055555555555555565/7187 7222 10413 10614 10753 6/28672-28673 28675 28677 28682 28684 28686-28687 28690 28692 28694-28697 28699 28701 28704-28705 28707 28709-28710 28712 28718-28720 28724 28726-28729 28731 28733-28734 28736-28737 28743 28745-28746 28754 28761 28763 28765-28766 28768-28769 28771 28775-28776 28780 28782-28784 28786 28788 28790-28792 28795 28797 28799-28801 28803 28805-28806 28809-28810 28812 28816 28818 28822-28823 28826-28829 28831 28834-28837 28839-28841 28843 28845-28846 28849 28851-28852 28856 28860 28862-28865 28867 28869 28873 28876 28878 28881-28882 28884 28886 28893 28895-28896 28898-28901 28903-28905 28907 28911 28915 28917-28918 28920 28922 28924 28926 28936 28942-28943 28960-28961 28963 28967 28969-28970 28972 28974 29058-29060 29065 29067 29088 29096 29098 29200-29201 29205 29251-29252 29254 29264 29266 29269-29271 29273 29277 37893-37895 37904 37907 37910 41471 41591 41594 41596 41598 41631 41647 41650 41658 41662 41669-41672 41674 41676-41678 41681 41683-41684 41687 41689-41690 41697 41699-41700 41706 41754 41756-41758 41761 41765 41767-41769 41771 41773 41775-41776 41778 41780 41785 41788 41795 41797 41799 41801-41803 41805 41809 41811 41813 41815 41817 41819 41821 41824 41826 41828-41829 41856 41858 41860 42154 42156 42158 42162 42166 42168 42170 42172 42174 42202 42206 42208 42210 42212 42214 42216 42218 42220 42222 42224 42226 42228 42230 42232 42327 42333 42356 42358-42359 42361 42363 42365-42366 42374 42376 42378 42380 42382 42386 42388 42390 42392 42394 42396-42397 42399-42400 42402 42404 42416-42417 42432 42434-42437 42439 42441 42443-42444 42446 42450 42454-42455 42461 42463 42469 42471 42479 42481-42482 42484 42490 42492 42494-42495 42497 42499-42500 42502 42505 42512 42516 43016 43019 43022 43025 43027-43028 43032 43041 43043-43044 43048 43050 47786 47790-47791 47803https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/632/A85?format=asciiInfrareddefaultJ/A+A/632/A85/listList of released tables (FITS and ascii formats)NRowsNumber of sources in the FITS tablemeta.numberintrecnoRecord number assigned by the VizieR team.
