Issue with my Stamps Results

I processed my interferograms and plotted the map but results are very bad. I think this has to do with my interferograms.
Here is my results after ps_plot(‘u-dm’) and ps_plot(‘u-dmo’)


can anyone guide me how to know which interferograms are bad and remove them. is there a code to eliminate which don’t meet certain thershold or physically remove them. But i have no idea how to visually identify bad interferograms from above results.
