[Bug]: AOI over 3 S1 SLC bursts not subsetting #162

Hi, I have an AOI that spans 3 bursts and I was following the tutorial for the Golden Valley to test the code.

It seems that the AOI is ignored on the plots in some ways compared to the example

However the PS function is calculated over the 3 bursts

I am planning to cut that corner as it is not useful so I have only 2 bursts but just to let you know.

System and software version:

OS: Ubuntu 22.04
PyGMTSAR version: 2024.8.2.post3

Yes, I see—the bounding box of the selected burst covers the area fully. You can add a buffer like AOI.buffer(0.05) to expand your Area of Interest (AOI). This issue is technically related to GMTSAR binaries used in Sentinel-1 preprocessing. I plan to develop my own Sentinel-1 preprocessor to address this and other issues (including saving significant disk space) when I have the time for this project.
