The magnitude analysis is performed on all .zip files in the current directory by running go_magnitude.sh which uses the settings of Makefile_magnitude.templateS1A.

The InSAR phase analysis is performed on all .zip pairs of a given satellite (A or C) by running go_phase.sh which uses the settings of Makefile_phase.templateS1C.

Tune parameters according to your needs:

• firstBurstIndex=6 and lastBurstIndex=6 of IW3 in Makefile_magnitude.templateS1A for Sentinel1A (also valid for 1C)

• ./DEM.tif for the DEM used for elevation correction
