Faint Standards for UKIDSS and VISTA ZYJHK

DOI

The currently defined 'United Kingdom Infrared Telescope (UKIRT) Faint Standards' have JHK magnitudes between 10 and 15, with K_median_=11.2. These stars will be too bright for the next generation of large telescopes. We have used multi-epoch observations taken as part of the UKIRT Infrared Deep Sky Survey (UKIDSS) and the Visible and Infrared Survey Telescope for Astronomy (VISTA) surveys to identify non-variable stars with JHK magnitudes in the range 16-19. The stars were selected from the UKIDSS Deep Extragalactic Survey and Ultra Deep Survey, the WFCAM calibration data (WFCAMCAL08B), the VISTA Deep Extragalactic Observations (VIDEO), and UltraVISTA. Sources selected from the near-infrared databases were paired with the Pan-STARRS Data Release 2 of optical to near-infrared photometry and the Gaia astrometric Data Release 2. Colour indices and other measurements were used to exclude sources that did not appear to be simple single stars. From an initial selection of 169 sources, we present a final sample of 81 standard stars with ZYJHK magnitudes, or a subset, each with 20 to 600 observations in each filter. The new standards have Ks_median_=17.5. The relative photometric uncertainty for the sample is <0.006mag and the absolute uncertainty is estimated to be ~<0.02mag. The sources are distributed equatorially and are accessible from both hemispheres.
