Notes for reducing XIS0 data with area discrimination after 2014-05-15.

2014-09-29 by the XIS team

After the XIS0 anomaly in June 2009, we observed a severe charge leakage in a part of the segment A of the XIS0. To mask the damaged area, we apply an area discrimination (AD) for all data starting from June 27, 2009 16:27 (UT).
Since some time between 2014-05-15 and 2014-06-02, the charge leakage area expanded. This is a night earth image integrated between June to September, 2014.
We decided to expand the area discrmination area from ACTX=70-110 to ACTX=0-210 since 2014-10-02 12:38 (UT). The new discriminated area is shown in the XIS quick reference. Other remarks are the same with the previous note.
