The Issue:
The default InSAR populate ONLY ONE co-pol offset products (HH first, VV second) because of the runconfig parameter (process_single_co_pol_offset) here. The InSAR writer mis-used the polarizations from the function get_cfg_freq_pols where the third returned parameters are the polarization from the offsets products, but it used the second return parameters. This triggers the inconsistency between the InSAR writer and offset products, which means that the VV offsets will be created in the InSAR products, but not in the offsets products.
The solution:
Update the InSAR writer to use the right polarizations being consistent with the offsets products.
The caveat:
how we will populate the listOfPolarizations in the RIFG, RUNW, and GUNW products? I mean the interferograms will have two co-polarizations, but the pixelOffsets will have one co-pol polarization, which might fail the QA?
