Subject:	SGP/ACSM/C1 - Instrument averaging time changed
DataStreams:	sgpaosacsmC1.00, sgpaosacsmC1.01, sgpaosacsmC1.a1, sgpaosacsmcalC1.b1, sgpaosacsmC1.b1
Description:	The number of sets collected in each data write was changed when the instrument was restarted on 2015-08-26. This resulted in a change in the averaging time from 30 minutes to 10 minutes. Users should be aware that the data during this period are 10 minute averages and not the standard 30 minute average. The original settings were restored on 2015-09-22 at 13:19. Other than the change in averaging time the data are unaffected.
Suggestions:	Be aware of the change in averaging time.
