Figure 3: Folded EPIC-PN light curves in the standard EPIC energy bands including the data from the three observations in Nov./Dec. 2005. The intensity profiles are normalized to the average count rate (in cts s-1: 0.0126, 0.0328, 0.0686, 0.0701, 0.0559, 0.241 from top to bottom) and include background (average levels of 0.0021, 0.0013, 0.0013, 0.0014, 0.0034, 0.0097 cts s-1). |
