The quality of the processed data in each SPD record is given in the SPD quality flag field `PxxSFLAG' where `xx' identifies the detectors as follows C1, C2, P1, P2, P3 SS, and SL. Table 7.3 gives the coding of each bit in the (8 bit) flag.
Bit | Description |
0 | nominal |
1 | calibration measurement saturated |
2 | part of plateau data affected by drift |
3 | all ramps on plateau rejected |
4 | plateau data affected by residual drift |
5 | zero standard deviation |
6 | empty |
7 | zero signal for plateau |
