Subject: | SGP/RL/C1 - Calibration problems in ASR |
DataStreams: | sgp10rlprofasr1ferrC1.c1, sgp10rlprofext1ferrC1.c1

Description: | During these times, identified through visual inspection of the time-height plots, the VAP
produced non-physical artifacts due to incorrectly derived calibrations. |
