The following table, courtesy of Dave Thompson, 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.
The K' magnitudes in the last column are interpolated. They should provide better numbers than assuming that the K magnitudes apply to data obtained with a K' filter.
Some modifications to the table have been made, for example notations on a number of stars that are double. A more up-to-date table of FS stars can be found at the Joint Astronomy Centre Web site, at
http://www.jach.hawaii.edu/UKIRT/astronomy/calib/phot_cal/fs_fundamental.html
This latter site contains cross references, spectral types, optical photometry, etc.

Flux for magnitude 0 star |
654 Jy |
1049 Jy |
1614 Jy |
Notes: FS24 is apparently a variable star!
FS 18, 25, and 28 are double stars.
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.
