Dear @mobigroup, analysis of Morocco earthquake showing phase jumps between bursts. I suppose this is from bad alignment, do you have a solution to this problem?

Please share the list of scenes for the case; I'll check it sometime later.

Yes, I can reproduce the issue you've mentioned. It's possible that the Enhanced Spectral Diversity (ESD) feature could help resolve it, though it's not guaranteed (it is not available in PyGMTSAR for now). I recommend trying it out to see if it offers any improvement in your case.
