C.6 From Revolution 64 (Late in the PV Phase)

1. Scan ranges in SWS01 adjusted, to increase the overlap and to optimise redundant coverage.
2. Dark-current measurements made longer, to improve the measurements.
3. Level-high photometric checks deleted, to avoid upsetting band 2, band 4 and FP detectors. This makes the checks useless for band 1, but that band is as stable as the internal calibrator source. The effect is better initial detector behaviour in AOTs executed immediately after another SWS AOT.
4. Reduced frequency of photometric checks, giving marginally better data quality in bands 2, 4, 5 and 6.
5. Fewer reference scans in SWS06, again giving marginally better data quality.
6. Resets limited to 1 or 2 seconds (instead of 1, 2, 4 or 8 seconds). In orbit, reset intervals of 2 seconds give the highest sensitivity, at least in bands 2-6. Longer intervals catch too many particle glitches.
7. Band limits of 3D, 3E and 4 adjusted, to minimise leakage from the second-order spectrum.
