Optical light curve (R-band) of PKS 2155-304 measured with ROTSE.
The light curve was observed from August 24th, 2003 till October 26th, 2010 with the ROTSE-III telescope system. ROTSE (2003PASP..115..132A) does not use an R-Band filter. The R-band magnitudes are rather cross calibrated with the magnitudes of hundreds of reference stars. Since the optical spectrum of PKS 2155-304 deviates from a star-like spectrum the measured luminosity deviates systematically. A cross calibration with the ATOM telescope (2004AN....325..659H) revealed that the ROTSE magnitude can be adjusted by subtracting 0.22 from the measured values: mR=mROTSE-0.22. (1 data file).
