2 Changes
Made several columns into vector columns so that we distinguish between inner and outer CCDs.
Although we initially thought that the outer MOS CCDs would always be in the FULL FRAME
mode, teh actual timing in most modes are synchronised to make the latter a multiple of inner CCD
readout time.
Also fixed the numerical value of window size and times for mode 6 (aka RFS) which were
incorrect
3 Scientific Impact of this Update
Modes should now be recognisably defined correctly for all cases and all CCDs.
Vector column usage should be backward compatible, as scalar value extraction will jus ttake
the first value of the vector column.

4 Estimated Scientific Quality
Any imprecision in mode­dependent EXPOSURE corrections are expected to be small compared
with the know deficiencies in effective area determination of CCDs and mirror.
5 Expected Updates
When new modes for different boresights are implemented, we expect to have small changes in mode
timings
