Cloud Data Access
------------------
-All public datasets from Hubble are also available on Amazon Web Services in a `public S3 bucket <https://registry.opendata.aws/hst/>`__. If you are using AWS resources to process public data you can take access these data in the following way. An `AWS credentials file <https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-files.html>`__ is required to access the data. Instructions on generating such credentials are available `here <https://stackoverflow.com/questions/21440709/how-do-i-get-aws-access-key-id-for-amazon>`__. The `~astroquery.mast.ObservationsClass.enable_cloud_dataset` function reads in the credentials. Next, the `~astroquery.mast.ObservationsClass.get_cloud_uris` function will return S3-like URLs the data products (e.g., s3://stpubdata/hst/public/icde/icde43l0q/icde43l0q_drz.fits). Finally, the cloud downloads can be disabled using `~astroquery.mast.ObservationsClass.disable_cloud_dataset`.
