Thanks @souravsingh. I think we will need to do a clean up of the git log as the commits related to astropy-helpers should probably be removed as they are not direct contributions to ccdproc.

[bsipocz]

@crawfordsm - I don't think it's necessary to hack the log and rewrite history.

The commits are coming from the package-template and not from astropy-helpers. Maybe the easiest would be to cross match the commit hashes against the template. The ones that don't match are ccdproc only.

[bsipocz]

Also, all commits before 9185b8b seems to be coming from the template.

[crawfordsm]

@souravsingh can you implement @bsipocz suggestion and see what the list returns? All the wording should be updated to reflect this is for ccdproc and not astropy

[souravsingh]

@crawfordsm I will get on to it.

[mwcraig]

Merging as-is, will open a separate PR in a few minutes to clean up the list.

Thanks, @souravsingh!
