Notes. LW and FW modes correspond to PN Large Window and Full Window, respectively. Exposure time and good time intervals (GTI) are shown in ks. The excision radii used in the pile-up treatment for each observation are indicated in arcsec and the columns “Rate” and “Color” correspond to the average count rate and soft/hard color ratio in the corresponding annular extraction regions.
