Subject: | SGP/NEPHELOMETER/C1 - Problem with the NEPH chopper motor |
DataStreams: | sgpaosnephdry1mC1.b1, sgpaosnephdryC1.b1, sgpaosnephdryC1.a1 |
Description: | The issue with NEPH chopper motor may make the data noisier. The problem is relying on an old calibration from the chopper for the fixed brightness object. The data are probably okay, but if something shifts in the system (e.g., lamp brightness) then it might not be. Highest quality data can be attained using data with neph flag=0000. |
Suggestions: | Use the nephelometer instrument flags to invalidate the 1s data when this is a problem. |
