The nominal exposure times (Cols.~4 and~5) are obtained from the 
observation log browser of the XMM-Newton archive 
({\tt http://xmm.vilspa.esa.es/external/xmm$_{-}$obs$_{-}$info/obs$_{-}$view$_{-}$frame.shtml}) 
for each detecter.  The total exposure times (Cols.~6 and~7) are the 
mean chip LIVETIMES read from the event file headers, and the cleaned 
times (Cols.~8 and~9) are obtained after the application of the 
two-step cleaning process described in the text. Columns~10 and~11 
give the cut values for the second, wider band cleaning in units of~cts~per~10~s. The flag indicates good cleaning (1), cleaning with 
standard cuts (2), imperfect cleaning with residual high background 
sufficient for the image analysis but not necessarily for spectroscopy 
(3), and cases where the exposure for one of the detectors has 
effectively been lost (0).
