[vsnet-chat 2074] BV sequence for V1333 Aql

[bas@lowell.Lowell.Edu (Brian Skiff)]

     While persuing the latest ApJ, I found a reference to a photometric
sequence for the x-ray binary V1333 Aql = Aql X-1 by Lyutyi & Shugarov.  Below
are positions for the stars and the BV data from Figure 1/Table II of the
paper in the format of my photometric reference file.  The authors claim 
uncertainties between 0.02 to 0.05 mag. except for the two faintest stars.
Note that the fainter stars are quite red.  The positions are from either
GSC v1.2 (not v1.1) or USNO-A2.0.
