These software is intended to correct unwrapped phases using GACOS grids for GMTSAR.
They have been tested with: GMT v6.1.0 GMTSAR v6.0
On "Test_against_matlab" folder, I perform comparisons with matlab with consistent results. To reproduce the output just use: source command.txt in each folder. There is a small README file in each folder
single_GACOS_correction.csh is intented to correct a single interferogram at a time with certain parameters
GACOS_correction.csh and operation.csh are used to correct a stack of interferograms in a time series process
Corrections are applied to the unwrap.grd files
Feel free to use and edit the code if needed
