No, not at all. But I know that a lot of astronomers live by it daily, and if we can say "this code agrees with what you are using to xxx precision and has been tested against it", it will assuage some.

Yes, definitely. The IDL script can't be run automatically anyway.

Hopefully our API is better. :)
So... can I get a volunteer to write the code that compares the results to the new astropy coordinates package? I might argue that it shouldn't be Adrian, Erik, or myself since we wrote the code, and it would be very valuable to have someone from the community use it to see how much sense it makes. This includes reading the examples and documentation to let us know if anything is unclear.
Really appreciate all the help and suggestions.
