Subject:	OLI/TRACEGAS/M1 - Data output changed to 0.5 Hz
DataStreams:	oliaoscoM1.a1, oliaoscoM1.00, oliaoscoM1.01, oliaoscoM1.b1
Description:	In an effort to diagnoses data dropouts, the instrument output rate was changed from 1 Hz to 0.5 Hz. Since the instrument averages over the reported time and the dynamic time response is ~2-5 s, there is no appreciable loss in S/N or time response. Once tests are completed on the virtual machine and the LGR instrument, the reporting speed will be returned to 1 Hz.
