Removed events
eSASS task EVPREP currently removes these events. Future eSASS version will only flag them and exclude them from the quality good time intervals (QUALGTI).
Duplicated events: events that are received with identical frame time and have the same RAWX and RAWY coordinates.
95 subsec events: events with SUBSEC values above 95.
Data/Time events: events with DATASRC or TIMESRC not equal zero.
ENV mode events: events with ENVSRC with non-NULL values.
Undefined PHA events: events with PHA undefined (NULL).
General statistics of removed events
69 eROdays have been processed with evprep. These eROdays lie within the 43068-43193 range (~26.08.19-16.09.19). The eROdays are chosen based on the CXFWPOS value in their respective HK-2 file: FWPOS=13 or FWPOS=8, for the whole duration of the eROday. eROdays with mixed CXFWPOS values are discarded for the moment.
Statistics for a single TM operating at a given eROday
The following histogram shows the percentage of removed data in each TM when only one camera is in operation at the time. Dark colours show CXFWPOS=8, i.e. with optical filter applied, while light colours show CXFWPOS=13, i.e. with calibration source.
TM2, TM4 have not operated alone so far. And TM5 did not operate alone with the filter.
