| Subject: | SGP/QCRAD/E13 - Multiplexer failure |
| DataStreams: | sgpqcrad1longE13.s2, sgpqcrad1longE13.s1, sgpqcrad1longE13.c1, sgpqcrad1longE13.c2
|
| Description: | The down_short_hemisp (PSP), down_long_hemisp_shaded (DIR) and up_long_hemisp (UIR)
experienced frequent dropouts due to a failing multiplexer. CM replaced mux on 1/7. Don't
use best estimate GSW, if "source_BestEstimate_down_short_hemisp" is -1.
