get_skyheader#

mufasa.master_fitter.get_skyheader(cube_header)[source]#

Generate a 2D sky projection header from a 3D spectral cube header.

This function extracts the celestial (spatial) WCS information from a 3D FITS header and constructs a 2D header suitable for spatial operations.

Parameters:: cube_header (astropy.io.fits.Header) – The FITS header of the 3D spectral cube, containing WCS information.
Returns:: A 2D FITS header containing only the celestial WCS information from the input 3D header.
Return type:: astropy.io.fits.Header

Notes

The function retains the spatial resolution and axis sizes (NAXIS1 and NAXIS2) from the input 3D header.
The returned header is useful for spatial projections and visualizations.

Examples

>>> from astropy.io import fits
>>> cube_header = fits.getheader("spectral_cube.fits")
>>> sky_header = get_skyheader(cube_header)
>>> print(sky_header)
