e) Expose and process 1 x 512 arc sec spatial sample (e.g. including readout time, compression) data in < 1s.
f) Allow exposure times in the range 100 ms - 300 s with an accuracy of 5 %. The ability to make shorter exposures, down to 50 ms with reduced accuracy, is desirable.
g) Perform automatic exposure control.
h) Perform data compression. The data compression is currently JPEG in the MDP, but the facility to include a different compression scheme e.g. H-compress, in the ICU should remain open.
It is required that the compression factor can be varied for different studies
