L2I Retracker Failure Flag Monitoring

IPF Baseline:
Phase:

Cryosat L2I data includes a Retracker Failure Flag for each 20Hz measurement record (Baseline A/B:L2I field 48, bit 0 Baseline C: L2I field 75 bits 20,21,22). This indicates the overall success or failure of the retracker algorithm for that measurement waveform.

This tool provides statistics of retracker failure and global and polar plots of the Retracker Failure Flag for each 30-day data take and SIRAL mode.
