Add support for GAMMA initial baseline estimates #329

Closed mcgarth closed 3 years ago

mcgarth commented 3 years ago

This PR adds support for reading and using the Initial baseline estimates from GAMMA *base.par files.

The Precise baseline estimate will be used if it is found (i.e. if one of the TCN components is non-zero), otherwise the Initial baseline estimates will be read.

This change is required to support interferograms where precise baseline estimation has been skipped (i.e. when the orbital state vectors are deemed adequate to solve for the orbital phase contribution. This is usually the case for Sentinel-1).
