How are the products generated?
During NSBAS processing, three phases can be recognized:
the Interfero phase: from the creation of working directory to the unwrapping step
the Time-Serie phase: time serie calculation
the Populate phase: generation of the products

Note
The InWF (unwrapped-filtered interferogram) and the Coh (spatial coherence) are used in the radar geometry (InWF_radar_rint and Coh_radar_rint) during the processing but only the geocoded version (InWF_geo_rint and Coh_geo_rint) is published.
