From this initial status, the RCS must then decide in an autonomous way to change or not the value of QUALITY_FLAG records, when transferring the quality information to the output RPW CDF. The RCS decision must rely on relevant data (i.e, QUALITY_BITMASK, other data, parent data, etc.) as explained in the next section.
| Warning |
|---|
The RCS cannot increase the value of a given QUALITY_FLAG record. Especially, the higher QUALITY_FLAG index (i.e. "4") is not used for L1/L1R/L2 CDF. For instance, if a given input RPW L1R CDF has a QUALITY_FLAG record value equals to "2", then the corresponding value in the output L2 CDF can be "2", "1" or "0" depending on the RCS QUALITY_FLAG computation. In another word, "bad quality" data records cannot become "good quality" data records along the L1 to L2 data processing path. |
Computation
The detailed computation of the QUALITY_FLAG for each RPW L1R/L2 data product must be given in the RCS Software Requirements Specification (SRS) documents (see RPW Calibration Software Documentation).
