Plot description: Histogram of the source flux averaged over s/c orbit (see lightcurve on the left). The flux bin [1,5] mCrab contains counts from range [-5,5] mCrab. The flux measurements with error >5 mCrab were dropped.
Plot description: The blue data points show source flux over one s/c orbit (3 days). The all time-averaged flux and corresponding 1σ errors are shown in red. The star symbol is shown when flux error is greater than 5 mCrab and detection significance is less than 3σ.
