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.
