Fig. 1

The 17 − 60 keV light curves (left) and histograms of the corresponding flux distribution (right) of two sources in the catalog: persistently detected and highly variable LMXB GX 349+2, and HMXB transient 4U 1901+03. The blue dotted lines in the left hand figures represent the flux of the sources measured on a 7-year time-averaged map. The first flux bin in the right histograms contains counts from the range [−5,5] mCrab, and the flux measurements with error > 5 mCrab were dropped.
