This function provides the NDDataBase interface to the astropy unified I/O layer. This allows easily reading a file in the supported data formats, for example:: >>> from astropy.nddata import CCDData >>> dat = CCDData.read('image.fits') Get help on the available readers for ``CCDData`` using the``help()`` method:: >>> CCDData.read.help() # Get help reading CCDData and list supported formats >>> CCDData.read.help('fits') # Get detailed help on CCDData FITS reader >>> CCDData.read.list_formats() # Print list of available formats See also: - https://docs.astropy.org/en/stable/nddata - https://docs.astropy.org/en/stable/io/unified.html Parameters ---------- *args : tuple, optional Positional arguments passed through to data reader. If supplied the first argument is the input filename. format : str, optional File format specifier. cache : bool, optional Caching behavior if file is a URL. **kwargs : dict, optional Keyword arguments passed through to data reader. Returns ------- out : `NDData` subclass NDData-basd object corresponding to file contents Notes ----- cstj||ddddS)Nreadrsuper__init__selfinstancecls __class__9lib/python3.9/site-packages/astropy/nddata/mixins/ndio.pyr 6szNDDataRead.__init__cOs|jj|jg|Ri|SN)rr_clsr argskwargsrrr__call__:szNDDataRead.__call____name__ __module__ __qualname____doc__r r __classcell__rrrrr s* cs(eZdZdZfddZddZZS)raWrite this CCDData object out in the specified format. This function provides the NDData interface to the astropy unified I/O layer. This allows easily writing a file in many supported data formats using syntax such as:: >>> from astropy.nddata import CCDData >>> dat = CCDData(np.zeros((12, 12)), unit='adu') # 12x12 image of zeros >>> dat.write('zeros.fits') Get help on the available writers for ``CCDData`` using the``help()`` method:: >>> CCDData.write.help() # Get help writing CCDData and list supported formats >>> CCDData.write.help('fits') # Get detailed help on CCDData FITS writer >>> CCDData.write.list_formats() # Print list of available formats See also: - https://docs.astropy.org/en/stable/nddata - https://docs.astropy.org/en/stable/io/unified.html Parameters ---------- *args : tuple, optional Positional arguments passed through to data writer. If supplied the first argument is the output filename. format : str, optional File format specifier. **kwargs : dict, optional Keyword arguments passed through to data writer.
