VizieR Online Data Catalog: Faint Standards for UKIDSS and VISTA ZYJHK (Leggett+, 2020)

The Northern hemisphere UKIDSS (with the WFCAM camera) and the Southern hemisphere VISTA use similar-size telescopes, and similar filters defined according to the Mauna Kea Observatories filter specifications (Tokunaga, Simons & Vacca 2002PASP..114..180T). Survey data generated by both telescopes are initially processed by the Cambridge Astronomy Survey Unit (CASU) and then transferred to the Wide-Field Astronomy Unit (WFAU) in Edinburgh for further processing and archiving (Hambly et al. 2008MNRAS.384..637H; Cross et al. 2012A&A...548A.119C). Table 1 gives a summary of the properties of the surveys used in this work.

We used the WFCAM Science Archive (http://wsa.roe.ac.uk) and the VISTA Science Archive (http://surveys.roe.ac.uk/vsa) to query the DXS, UDS, UltraVISTA, VIDEO and WFCAMCAL databases.

Our goal is to identify stars that are not variable, that have well-measured JHK magnitudes, and are fainter than K=16. Therefore we only used surveys with variability tables for all of the J, H, and K filters.
