It would be good if make_fitswcs_header took an observer coordinate as input, and put it into hgln_obs etc. keywords in the fits header.

We should have a mock document template with fields that require user input (name, signature, etc) that can be filled easily using something like Docusign. The wording if the template would require input from experts but we could have a dummy template along with relevant RPC handlers required in order to do this.
