Currently, only the Corner and Ratio methods described above operate as required. The Corner method effectively cuts the light curve at some number of sigma above the mean nominal level and the Ratio method compares the count-rate per unit area in the obscured corners of the detector to the same in a FOV annulus within the 8-12 keV band.
One future “method” may include one that determines a fixed count rate plus some “delta”. In this case, the high energy count rate, say 8-12 keV, is created and the user selects an appropriate threshold. This will be the “delta method”. This method should be able to select the light curve produced by the PPS which are point source excluded (*FBKTSR* files).
The task leaves open the possibility to add new "methods" in future releases.
