@rmandelb just checking if I understand the goal here. We want to keep the current setting that if `sample` is given, the catalogs to be read must be named `real_galaxy_catalog_sample.fits`,`real_galaxy_catalog_sample_fits.fits`,...

Just realized I made an error in my own naming scheme. Catalog with any other name to be read, should be input with `file_name='any_other_name.fits'`, and the catalogs to be read...

The second part with `file_name` kwarg, the name must have a SAMPLE value: `file_name='any_other_name_SAMPLE.fits'`, and the catalogs to be read will be `any_other_name_SAMPLE.fits`, `any_other_name_SAMPLE_fits.fits` and `any_other_name_SAMPLE_selection.fits`. We need to be...

A basic version implemented in Implemented in [#13](https://github.com/LSSTDESC/BlendingToolKit/pull/13) which compares detected centers and true centers.

@ismael2395 I was thinking an extension of example 4 in this [notebook](https://github.com/LSSTDESC/BlendingToolKit/blob/9e4f0d5fa175592ebd646e433fbc87bcdf9a0d46/notebooks/custom_sampling_function.ipynb). Here galaxies within a certain threshold radius of a central galaxy are classified as part of the blend....
