UKIRT Faint Infrared Standard Stars

The following table contains the UKIRT faint standard stars from Casali (1992 UKIRT Newsletter, 4, 33). Links on the names brings up a K' image 4 arcminutes square, with North up and East to the left. The standard star is indicated by the tick marks. If you manage to get a decent image in any K-band filter (K, Ks, K') for any of the stars on this page currently without finding charts, I would appreciate receiving a copy so I can include it here. Please contact me via email at <<djt@mpia-hd.mpg.de>>.

There is also a table of interpolated K' magnitudes available. While these numbers were not obtained through proper calibration, I have found them to be a little better than simply assuming the K-band magnitude applies to observations obtained with the K' filter.

¤ Denotes a white dwarf star. FS24 is apparently a variable star!

Flux for a 0.0 magnitude star (Jy) 654 1049 1614

Note: The values quoted above for the flux from a zero magnitude star are from Bessel & Brett (1988 PASP, 100, 1134), scaled to zero magnitude. Bessel & Brett quote fluxes for a 0.03 magnitude star.
