Alignment and rotation of satellite galaxies and stellar particles

Dear Dylan,
I am working with the TNG50-1 data to calculate orbit distributions of galaxies and am planning to incorporate information from the mergers as well. To do that, it is necessary to align the satellite galaxy and the stellar particles of the main galaxy within the same coordinate system at every snapshot. I am therefore writing to ask if there exist any pre-computed alignment matrices calculated based on the stellar particles?
I have been looking into the supplementary data for the stellar circularities, however these only contain the information of the eigenvalues. Does there also exist the information on the corresponding eigenvectors?
All the best,
Stefanie

Perhaps the discussion and code in this thread will be useful.
