Reduce the PS points while running the stamps(6,6) or stamps(7,7)

I just processed 127 interferograms and around 1800000 PS points are generated using D_A value at 0.5. While plotting the unwrapped phase it is giving error (out of memory). So I wanna reduced PS points at the stage of stamps(6,6) and stamps(7,7).
Because running all the stamps steps are time-consuming. So please give an idea to reduce the count of PS points?

Steps 6 and 7 remove look angle errors based on different geometric assumptions.
The reduction of points is done in earlier steps (amplitude dispersion in mt_prep, maximum
fraction of random phase pixels in step 3, weeding in step 4).
The variables are explained here: StaMPS/ · master · Matthias Schlögl / gis-blog · GitLab

I’m afraid you have to go some steps back to reduce the data volume.
