classmethod

astropy.io.fits.hdu.hdulist:HDUList.fromstring

source: /astropy/io/fits/hdu/hdulist.py :499

Summary

Creates an HDUList instance from a string or other in-memory data buffer containing an entire FITS file. Similar to HDUList.fromfile, but does not accept the mode or memmap arguments, as they are only relevant to reading from a file on disk.

Extended Summary

This is useful for interfacing with other libraries such as CFITSIO, and may also be useful for streaming applications.

Parameters

data : str, buffer-like, etc.

A string or other memory buffer containing an entire FITS file. Buffer-like objects include ~bytes, ~bytearray, ~memoryview, and ndarray. It should be noted that if that memory is read-only (such as a Python string) the returned HDUList's data portions will also be read-only.

**kwargs : dict

Optional keyword arguments. See astropy.io.fits.open for details.

Returns

hdul : HDUList

An HDUList object representing the in-memory FITS file.
