Subject:	ENA/UHSAS/C1/S1 - Reprocess: Incorrect sample accumulation time
Affected Datastreams:	enaaosuhsasS1.a1
Description	During the deployment of the UHSAS at the satellite site the instruments at both the main and the satellite sites have been configured to accumulate the data at a 1-second rate instead of the normal configuration of 10-seconds. To make this configuration transparent to the data collection by the DMF a special version of the VI has been running that sums the counts and averages other values. One value, "sample_accumulation_time" should have been summed, but it was being averaged. This has been corrected in the program but the files that were written need to be corrected and then reprocessed.
Measurements	sample_accumulation_time (Sample accumulation time)

Subject:	ENA/ACSM/C1 - Filament and detector voltages off
Affected Datastreams:	enaaosacsmC1.a1
