| Subject: | SGP/MWR/B5 - wrong calibration |
| DataStreams: | sgpmwrlosB5.00, sgp5mwravgB5.c1, sgpmwrlosB5.a1, sgpmwrlosB5.b1, sgpmwrtipB5.a1
|
| Description: | An upgrade of the instrument by the manufacturer significantly changed its
calibration and the configuration file was not updated with the new calibration
values when the instrument was returned to service. |
| Suggestions: | Reprocess the data with the correct calibration. |
