2 Changes
Version 13 of the MOS bad pixels CCFs intends mostly to mask in the SAS (i.e. on­ground only)
the defects (high­pHA hot pixels) created by the impact of the micro­meteorite in rev 325 on MOS1
CCD6 and 7. It also incorporates some hot pixels that have developed with the last solar flares.
Version 14, is a replication of the update of the on­board table of bright pixels, uploaded at the
start of rev 361. Therefore the only difference with version 13 is that some pixels that were masked
on­ground (''H'' in CCF) are now masked on­board (''h'' in CCF)

3 Scientific Impact of this Update
4 Estimated Scientific Quality
5 Expected Updates
Whenever there is a new release of badpixels for on­board the CCF file will be updated. Not­uplinked
bad pixels which are found to be stable should be added in the future.
