The Prep Baseline values calculated from the SNAP software and the command line are not matching. The dataset used is the same.
are the orbits used identical too?
I dn’t know how snap command line process the data.
I may be wrong but based on your screenshots, I have the feeling that SNAP computed the perp baseline with the precise orbits with GPT (see the _orb suffix) but without precise orbits in your stack overview (directly on your zipped data).
