[Crater-team] Sorting CRaTER data using information in the Level 1 Secondary files

[Mark D Looper]

Hello—

                I’m sorry I missed the telecon this morning; I dialed in fifteen minutes late, but I guess you had already finished.  Anyway, I have been digging through the clues in the Level 1 Secondary science data files to see if I could find a way to sort SEP data rigorously among the different modes, and I have put together an _almost_ complete picture as detailed in the attached brief PPTX.  Information in these files can also be used to trim out periods in calibration or other non-nominal operating states; previously I just looked for clusters of calibration events in direct-event plots of D2 vs. D4 pulse heights (or other pairs) and rejected whole days’ data if such clusters appeared, but I would like to be more selective in discarding data once I start producing the scrubbed cosmic-ray and SEP triples H and He time series that I’ve been talking about for a long time (as well as the albedo proton data, which I still need to pin down better).

Good hunting—
