10. `cpl.dfs` DFS header parsing¶

class cpl.dfs.ProcessingInfo(source, recno=-1)¶

Support for reading input files and parameters from the FITS header of a CPL processed file.

This is done through the FITS headers that were written by the DFS function called within the processing recipe.

calib¶

Calibration frames from a FITS file processed with CPL. The result of this function may directly set as cpl.Recipe.calib attribute:

import cpl
myrecipe = cpl.Recipe('muse_bias')
myrecipe.calib = cpl.dfs.ProcessingInfo('MASTER_BIAS_0.fits').calib

Note

This will not work properly for files that had astropy.io.fits.HDUList inputs since they have assigned a temporary file name only.

raw¶: Raw (input) frames

Note

This will not work properly for files that had astropy.io.fits.HDUList inputs since they have assigned a temporary file name only.

param¶

Processing parameters. The result of this function may directly set as cpl.Recipe.param attribute:

import cpl
myrecipe = cpl.Recipe('muse_bias')
myrecipe.param = cpl.dfs.ProcessingInfo('MASTER_BIAS_0.fits').param

md5sum¶: MD5 sum of the data portions of the output file (header keyword ‘DATAMD5’).

md5sums¶: MD5 sums of the input and calibration files. dict with the file name as key and the corresponding MD5 sum as value.

Note

Due to a design decision in CPL, the raw input files are not accompanied with the MD5 sum.

ProcessingInfo.__init__(source, recno=-1)¶

Parameters:	source (`str` or `astropy.io.fits.HDUList` or `astropy.io.fits.PrimaryHDU` or `astropy.io.fits.Header`) – Object pointing to the result file header recno (`int`) – Record number. Optional. If not given, the last record (with the highest record number) is used.
