GAMMA to Miaplpy, what does folder baselines use for?

[HN-Jiang]

Regarding this issue, I would like to ask: referring to the example PichinchaSenDT142_gamma, what is the role of the baselines folder in the data preparation? The example seems to use 20171012 as the super master image to generate .base_perp files in GAMMA using the PS method. Back in Miaplpy, miaplpy.load.baselineDir = ../baselines/ is used as the input.

However, in my case, I conducted two experiments. In the first one, I created .base_perp files for all interferogram pairs in the SBAS network (503 pairs). In the second one, I used 20160529 as the master image and created .base_perp files for the entire dataset using the PS method (76 files). But in Miaplpy's phase_linking step, it automatically adopts a different date as the master image for the calculation(20170301).

I provide the screenshot of my PS network in GAMMA and Miaplpy's network for phase linking step

I want to know if this will introduce errors into the phase_linking calculation? It seems that in both cases, the program did not use the .base_perp files I prepared in the baselines folder.
