How to provide the bad pixels
Two sources of bad pixels are considered here:
- the CCF; because the pipeline processing takes place within days
of the observation, the CCF at the time of processing is necessarily
always late (i.e. it was built on the basis of previous
observations). A few months later, the user may note that the
applicable bad pixels file (listed in the calibration index file
generated by cifbuild) has changed.
- bad pixels files; those may be obtained from the merged events list
by running emeventsproj
and embadpixfind
for MOS,
or badpixfind
for PN,
with user-defined settings and energy or time selection.
They may also be written manually (respecting the same format
described in badpix).
Another possibility is to take the BADPIXnn tables from
another events list.
