RXTE light curve used as input for each tpho component calculation with the same starting data point from 1800 MJD. We show the part of the light curve within 14 days before the Chandra observation (red dot) corresponding to each component. The markers are similar to Fig. 3. The time resolution (t_bin) in units of seconds was defined by the time difference between the Chandra observation and the last RXTE observation before it.
