Some feedback after testing tutorial notebooks C session

[lgong6g]

C1:

1. A naive question: how is the "depth" reflected in the fits file creation for i band? By decreasing the canvas_size argument?

C2:

1. For me it would be better if the transformation from the synthetic images to MEDS files can have more explanation content. Such as what is "nimage"? What elements are essentially needed in the "obj_data" and "image_info"? When we call methods from the MEDS object, what are the first two positional arguments?

C3:

1. When running the command: mcal.multi_mcal(infodicts, nprocess=nprocess), an error is returned saying that "index 37006 is out of the axis with size 10001" but in a second run the code works again. Though the accuracy of metalcal shear results are not very good compared to the fiducial values.

Thanks for the comments!

I think the item with C3 still needs some investigation, for now I simplified the example to focus on a shape noise free scenario

Ok, I got C3 figured out, the PSFex model had something wrong going on,

replaced it with a truth PSF model from galsim

Now works as intended
