`astropy.io.fits.hdu.base:_BaseHDU.writeto`

source: /astropy/io/fits/hdu/base.py :369

Signature

   def     writeto (    self    ,    name    ,    output_verify    =  exception   ,    overwrite    =  False   ,    checksum    =  False     )

Summary

Write the HDU to a new file. This is a convenience method to provide a user easier output interface if only one HDU needs to be written to a file.

Parameters

name : path-like or file-like: Output FITS file. If the file object is already opened, it must be opened in a writeable mode.
output_verify : str: Output verification option. Must be one of "fix", "silentfix", "ignore", "warn", or "exception". May also be any combination of "fix" or "silentfix" with "+ignore", "+warn", or "+exception" (e.g. "fix+warn"). See astropy:verify for more info.
overwrite : bool, optional: If True, overwrite the output file if it exists. Raises an OSError if False and the output file exists. Default is False.
checksum : bool: When True adds both DATASUM and CHECKSUM cards to the header of the HDU when written to the file.

Notes

gzip, zip and bzip2 compression algorithms are natively supported. Compression mode is determined from the filename extension ('.gz', '.zip' or '.bz2' respectively). It is also possible to pass a compressed file object, e.g. gzip.GzipFile.
