A Python Script I made to split a starfield image into several layers.
A Python Script I made to split a starfield image into several layers.
To be able to use the script, PixInsight with an installed Gaia data catalogue is required, as it needs the exported astrometry data text file.
Warning: I found an error if the DR position is on the southern hemisphere. The PUB249 pdf files did not show this error and are correct (as far as I checked). All Revisions 8+ and the Windows release have been fixed.
This Python TK application calculates a good set of stars for a 3 star fix, makes all calculations similar to the FAAs Celestial Computation Sheet (see FAA doc FAA-H-8083-18).
...It is written in Python and can be executed from the command line.
New release is version v0.5. Updated to be compatible with numpy version 1.12.
New release is version v0.4. It's now compatible with astropy for fits I/O and computation time is reduced by a factor of 2.
