Monitoring of X-Ray Sources in the Optical Spectral Region
Figure 2
Relation between the outburst light curves of GK Per in the optical (a) and X-ray (1.5–12 keV) (b) passbands. The optical data are from the AFOEV database, while the X-ray ones were obtained by ASM/RXTE. The smooth line in (a) represents the fit by the code HEC13. The thick lines in (b) denote the smoothing by the moving averages. The dashed vertical lines mark the times of the onset and the maximum light of the outburst in the optical region.
