Decide how to check observations with commanded 0 dither during acq #284

Open jeanconn opened 5 years ago

For observations with monitor windows and observations approaching a dark cal, there can be acquisitions during the interval when commanded dither is 0 ampl or dither disable. Should starcheck use the previous dither (which may be the effective dither at the time of acquisition)?

For starcheck 13.0 it will be feeding proseco.get_acq_catalog with the commanded dither for these rare special-case observations.

Can this be closed? It looks like the decision has been made e.g. in 21681 in MAY1319.

I don't think we should close this, because IIRC, you weren't happy with the 0 choice? It is in the noise, but I think we should probably have a separate pad or some such because your point was that commanded 0 dither does not mean instantaneous 0 motion. But super low priority.
