In case anyone can use them, here are photoelectric V and b-y (Stromgren)
for several comparison stars near KU Cas. These were measured September 1992
using the Lowell 53cm photometric telescope. The second line of each entry
gives the standard deviation of the two measures in each mean. The faintest
star was measured on only one night, and the values listed are uncertain by
perhaps +/- 20 percent: this star is really much too faint to measure
reliably with this aperture and Stromgren filters. The other stars are
contained on the preliminary "sample" AAVSO chart made February 1991.
Comparison with the magnitudes there suggests a small zero-point error (the
chart magnitudes are 0.1-0.3 too bright) at least down to mag. 13.5 or so.
