2 Changes
Add a second value (25 or 0) as accepted values for EPIC­MOS1 parameters E1410­1413 (EMOS1
EDU 6/7 NODE 0/1 THRES corresponding to CCD3+6) starting from VALDATE 2014­01­27T18:00:00.
In rev. 2589 (2014­01­27T17:43:55) the annual test of the inactive EMOS1 CCDs3+6 was
performed, therefore EDU6+7 were switched o# (=set to zero) for taking diagnostics of EMOS1
CCDs3+6. After the test, a ''fast EDU setup'' was done which did not set EDU6+7 back to value
25. As CCDs3+6 are not used any more, this fast EDU setup is also used in other activities, es­
pecially in the setup of the usual observation modes (FF, LW, SW, etc.). Therefore the values of
EDU6+7 stay zero until commanded manually to 25 again.
The XMM­Newton SOC standard processing pipeline stopped processing EPIC­MOS1 data be­
cause hkgtigen returned empty GTI tables (as all EDU thresholds must be equal 25 according to
EMOS1 HK PARMINT 0009.CCF). As EMOS1 CCDs3+6 are not used any more due to micro­
meteorite impact damages we surround this problem until these EDU6+7 parameters are set to
25 again, by also accepting value zero starting from just after the diagnostic exposures ObsID
2589 9999993571 and before observation ObsID 2589 0724940101.

3 Scientific Impact of this Update
None.
4 Estimated Scientific Quality
5 Test procedures & results
This CCF was tested on the observation for which the pipeline stopped the first time (ObsID
2590 0720700301) and the HK GTI file contained entries for all parameters including E1410­E1413.
