[vsnet-chat 4665] WZ Sge UBVRI field photometry

[aah@nofs.navy.mil]

I've placed on
http://ftp.nofs.navy.mil/pub/outgoing/aah/sequence/wzsge.bright.dat
a single-night UBVRI calibration of the WZ Sge field,
emphasizing only the bright stars within my 11x11arcmin field.
The zero point error for this file is in the 0.02mag range.
The bright comparison star to the SW of WZ Sge was reported by
Brian Skiff as (Krzemenski & Kraft 1964ApJ...140..921K):
    V =  8.76, B-V = 0.16, and U-B = 0.13; estimated R = 8.64
    
my single-night measures give:
         V     B-V    U-B    V-R    R-I
        8.719  0.174  0.146  0.044  0.089
in rough agreement with K&K.  In particular, R for this star is 8.67,
close to Brian's estimate.
