PS not available if scan stopped. #162

Closed ambarb closed 7 years ago

ambarb commented 7 years ago

Often stop scans to not collect useless data. Is there a way to retain the peak stats?

Something is odd, it should be firing on the stop. @gjwillms reported something similar...

Do those headers have stop documents in the database?

If you call gs.PS.compute() to force the computation. You can also make a PeakStats object and restream the data from databroker back through it.
