That is turned off. You can set the the following filename to generate it before running step rdr2geo: https://github.com/isce-framework/isce2/blob/main/components/isceobj/Alos2Proc/runRdr2Geo.py#L82

It might be caused by ionosphere. It would be helpful to look at the merged ESD interferogram.

these are lower and upper band interferograms used for ionospheric phase calculation using range split-spectrum method. For your purpose, the following parameters in input file should be True: ``` False...

Hi Roghayeh, This was caused by some bad azimuth offsets used for resampling in coregistration. You can go to one of the subswath processing folder, e.g. f1_*/s* You will see...

Hi Roghayeh, I saw you plotted the offsets with range pixel number as abscissa. Perhaps you can also try azimuth pixel number. You can also look at the interferogram/coherence to...

PS: the line interval of mosaicked interferogram/coherence are line interval of first swath * number of looks. You can also use insar/*_az.off to get rid of bad offsets, they do...

I agree with Eric. The ionosphere in this pair is too strong to correct for. The difficulty is mainly the spatially fast varying ionosphere patterns plus its large magnitude. Coregistration...

Eric is right. The problem is still culling the azimuth offsets. If you are unable to determine the correct offsets, you can use alos2App.py to calculate the geometrical offsets. The...

> > Hi @rtburns-jpl and @hfattahi, can this PR be merged since it contains important tools for estimating and correcting ionosphere in Sentinel-1 IFG stack? It also contains fixes in...

Thank you guys for all the tests and bug fixes. I have also updated baseline computation in alos2App.py and alos2burstApp.py. See details in pull requst #145.
