1 CCF Components
Name of CCF VALDATE EVALDATE Blocks CAL XSCS Flag
Changed Version
EPN BADPIX 0144.CCF 2011­12­21T10:05:34 BADPIX NO
2 Changes
Updated BPT CODE header keyword which reflects the version identification of the currently up­
loaded Bad Pixel Table (in systematic use from revolution 2204 onwards).
3 Scientific Impact of this Update
As the Bad Pixel Table itself remains unchanged, there is no scientific impact.
4 Estimated Scientific Quality
Note that in all the EPIC cameras there are intermittent bad pixels that may arise in only one
exposure. The user is recommended to run the bad pixel finding algorithm, and remove after
processing.
