Hi all,
I am new to StaMPS. I used StaMPS for my analysis. I completed the analysis from step 1 to step 7 (I did not do the atmospheric filtering).
However, when I looked at my velocity map. I found something weird happened, it seems there is a straight line across my velocity map, as shown below. The velocity is small, from -3.8 to 2.7mm/year.

(this is the 'v-do' plot)
I checked one of the unwrapped interferograms, there is no line in the unwrapped phase

(this is the 'u-dmo' plot)
Does anyone have an idea which step of my analysis is wrong? I used most of the default parameters for the analysis, except for the weed standard deviation as 0.8 (default is 1)
Appreciate your response and time.
Thank you.
Regards,
