ftsdata.fits_ftsdata_writer(fts_data, filename, hdu_mask='MASK', hdu_uncertainty='UNCERT', hdu_hits='HITS', hdu_flags=None, key_uncertainty_type='UTYPE', compress=False, **kwd)[source]

Write FTSData object to FITS file.

Parameters:
filenamestr

Name of file.

hdu_mask, hdu_uncertainty, hdu_hits, hdu_flagsstr or None, optional

If it is a string append this attribute to the HDUList as ImageHDU with the string as extension name. Flags are not supported at this time. If None this attribute is not appended. Default is 'MASK' for mask, 'UNCERT' for uncertainty 'HITS' for hits and None for flags.

key_uncertainty_typestr, optional

The header key name for the class name of the uncertainty (if any) that is used to store the uncertainty type in the uncertainty hdu. Default is UTYPE.

compressbool, optional

Use tiled compression ImageHDU for the data. Default is False.

kwd

All additional keywords are passed to astropy.io.fits

Raises:
ValueError

  • If self.mask is set but not a numpy.ndarray.

  • If self.uncertainty is set but not a StdDevUncertainty.

  • If self.uncertainty is set but has another unit then self.data.

NotImplementedError

Saving flags is not supported.
