L2 SST Data Quality Flag Descriptions

There is a data_quality flag variable associated with each SST L2 data type. (Data types include: 'psif' = Particle SST Ion Full mode, 'psef'= Particle SST Electron Full mode, 'psir' = Particle SST Ion Reduced mode, 'pser' = Particle SST Electron Reduced mode, 'psib' = Particle SST Ion Burst mode, 'pser' = Particle SST Electron Full mode. Full mode denotes low time resolution, high angular resolution data. Reduced mode denotes high time resolution, low (or no) angular resolution data, and Burst mode denotes high time resolution, high angular resolution data. For information on the SST instrument, please read instrument_sst.shtml. An example data quality variable name is 'tha_psif_data_quality', for THEMIS A. For each data type, a flag value of 0 indicates that the data currently has no issues. A non-zero value for the flag means that there may be problems. Non-zero values are totals of the values described below.

For each data type:

Flag Value 0 = Okay data.

Flag Value 1 = Counter saturation detected in raw data. This is set if the count rate for the given data type is greater than 10000 counts/second.

Flag Value 2 = Attenuator error, stuck attenuator or incorrect attenuator indicator.

Flag Value 4 = Spin period too low (less than 2.5 seconds) or too high (greater than 5 seconds). The nominal spin period is 3 seconds.

Flag Value 8 = Earth shadow

Flag Value 16 = Lunar shadow
