Python utility for FITS file handling.

This tool needs Python 3.

Other requirements:

Usage: python {list|move|header|coordinates|filter|summary|decompress} [file]

File name can have wildcards. Default is *.fit*.


Move option

If you are mixing images with different resolution and are using a tool like Pixinsight Blink then move option can be useful. Blink process does not seem to like images with different resolutions.

Command ‘python move’ finds X and Y resolution of .fit image from FITS keywords, automatically creates a XRESxYRES directory for each found resolution and moves .fit files to directory matching that resolution. After that it is easy to find images by resolution and run Blink on those.

Coordinates option

If you have a set of coordinate missions for example for mosaic but do not know what area they actually cover then coordinates option can be useful. Command ‘python coordinates’ recursively goes through subdirectories and finds all .fit files where coordinate information is encoded into the file name in format HHMMDD{p|n}HHMMDD.

Found coordinates are printed as a comma separated list. That list can be copied into Astro Mosaic tool target box to see what panels are available.

If you are mixing different telescopes then some panels are not correct since telescope information is not available at this format.
