Issue with not providing star shifts

[dnc7309]

Hello, I am trying to determine whether RCA can be utilized with my data set, but I have been hitting some issues. Currently, I am trying to load my own data set into the fit function, but I keep getting an error related to an empty argument called obs_pos. I saw this was resolved in the v2 of RCA where I can now provide a rough estimate of the psf size, but this has not solved the issue.

Hi!

The obs_pos argument contains the position of each object within the focal plane of the instrument. It is indeed necessary to pass on a list of coordinates of the same length as the number of objects (stars) used to estimate the PSF model.

Does that help at all?
