save_map#

mufasa.master_fitter.save_map(map, header, savename, overwrite=True)[source]#

Save a 2D map as a FITS file.

Parameters:

  • map (numpy.ndarray) – The 2D array containing the map data to be saved.

  • header (astropy.io.fits.Header) – The FITS header to include with the saved map.

  • savename (str) – The file path where the FITS file will be saved.

  • overwrite (bool, optional) – Whether to overwrite an existing file with the same name. Defaults to True.

Return type:

None

Notes

  • This function creates a Primary HDU with the given data and header and writes it to the specified file.

  • If overwrite is set to False and a file with the same name exists, an OSError will be raised.

Examples

>>> from astropy.io import fits
>>> import numpy as np
>>> data = np.random.random((100, 100))
>>> hdr = fits.Header()
>>> hdr['BUNIT'] = 'K'  # Example header keyword
>>> save_map(data, hdr, 'output_map.fits')
>>> # Saves `data` with the specified header to 'output_map.fits'.
