Subject:
SGP/RL/C1 - Alignment malfunction resulting in poor signal-to-noise ratio
DataStreams:sgprlC1.a0, sgprlC1.00
Description:
The signal-to-noise ratio was poor during the effected period due to a malfunction of the 
alignment system. This was probably caused by a problem in the stepper motor that 
controls the beam steering mirror.
Suggestions: 
Users should avoid using data during this period.
