Description:
2482 BVRI photometric data on eight red blazars taken from 3
Observatories in the period 2003 September - 2004 February are
presented. A table is given, containing the source name, the
observation time, the source magnitude, the error on the source
magnitude, the photometric band, and a label indicating the
Observatory where the observation was done.
