Here we compare Astropy coordinate transformation results against other Python coordinate packages.

For now we only compare precision, in the future we also want to compare speed.

The automatic deploying to gh-pages was set up by first generating an ssh key with:

ssh-keygen -t rsa -b 4096 -C "astropy.team@gmail.com" -f github_deploy_key -N ''

The github_deploy_key.pub public key was added as a deploy key in this repository (with write access). The travis command was then used to encrypt the private key:

travis encrypt-file github_deploy_key

The github_deploy_key.enc file was added to the repository, and the following lines were added to .travis.yml (the first line should be whatever is output by the travis encrypt-file command):

openssl aes-256-cbc -K $encrypted_ae4bff0a7007_key -iv $encrypted_ae4bff0a7007_iv -in github_deploy_key.enc -out ~/.ssh/publish-key -d
chmod u=rw,og= ~/.ssh/publish-key
echo "Host github.com" >> ~/.ssh/config
echo "  IdentityFile ~/.ssh/publish-key" >> ~/.ssh/config
