Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipes/tabsim/recipe.yaml) and found it was in an excellent condition.

I do have some suggestions for making it better though...

For recipes/tabsim/recipe.yaml:

• ℹ️ Recipes should usually depend on astropy-base as opposed to astropy. astropy-base only has the required dependancies whereas astropy now has all optional dependancies as well.
