I've moved to codacy from lgtm. See the dust_extinction package for an example. We could do this for PAHFIT.

Wouldn't mind learning about github scanning though.

Where does this issue stand? Do we still need to move? Our testing framework is rather broken at the moment, but I know @drvdputt has that on his plate.

I just updated the title of this issue. We can write down everything going wrong with the continuous integration services we're using, so we can fix it all in one pull request or a set close-in-time pull requests. Summary for now

• LGTM doesn't exist anymore. We should move to Codacy or Github code scanning. The latter seems quite straightforward. Not sure if it does the same as Codacy, but we can give it a try https://docs.github.com/en/code-security/code-scanning/enabling-code-scanning/configuring-default-setup-for-code-scanning#configuring-default-setup-for-a-repository
• Codecov was not working for Fitter API and make test cases work #289 . Says Rate limit reached. Please upload with the Codecov repository upload token to resolve issue.
