Subject:	SGP/MFRSR/E1 - Instrument maintenance
DataStreams:	sgpmfrsrE1.b1, sgpmfrsrE1.a0
Description:	Coinciding with a tech visit to the site, the instrument suffered a step function in the data. After the "step" the relative intensities dropped across all channels, and the relative position changed for channel 415 as well. Investigation into the cause of the step has yielded no answers. In the end this will likely be nothing more than a curiosity as the Langley plots and calibrations are not dependent on absolute calibration.
Suggestions:	Users should be aware of the step function in the data.
