L2I LRM Retracker: CFI vs OCOG Usage

In Baselines A and B, Cryosat L2I data included a Flag (L2I field 48: SS bit 31) to indicate whether the CFI or OCOG retracker was used for each 20Hz measurement record in LRM mode.

This tool provides statistics of which retracker was used and global and polar plots of the retracker usage for each 30-day data take.
