Note with a Python implementation to convert image coordinates to celestial coordinates using WCS TAN projection

[prajwel]

I have written a short note with a Python implementation to convert image coordinates to celestial coordinates using World Coordinate System (WCS) Gnomonic (TAN) projection. I hope it will be useful to someone. The PDF file can be accessed at link.

The source file is accessible at link.
