Use this function to facilitate batch runs.

This routine performs the remaining series of tasks in the UVIS pipeline. The wf32d primary functions include:

  • DARKCORR: dark current subtraction

  • FLATCORR: flat-fielding and conversion to electrons

  • SHADCORR: apply shutter shading correction (currently skipped)

  • PHOTCORR: photometric keyword calculations

  • FLUXCORR: photometric normalization of the UVIS1 and UVIS2 chips

Only those steps with a switch value of PERFORM in the input files will be executed, after which the switch will be set to COMPLETE in the corresponding output files. See Section 3.4.3 of the WFC3 Data Handbook for more information.

Running wf32d from a Python Terminal

from wfc3tools import wf32d

Displaying output from wf32d in a Jupyter Notebook

When calling wf32d from a Jupyter notebook, informational text output from the underlying wf32d.e program will be passed through print as the calibration runs by default, and show up in the user’s cell. This behavior can be customized by passing your own function as the log_func keyword argument to wf32d. As output is read from the underlying program, the wf32d Python wrapper will call log_func with the contents of each line. print is an obvious choice for a log function, but this also provides a way to connect wf32d to the Python logging system by passing the logging.debug function or similar.

If log_func=None is passed, informational text output from the underlying program will be ignored, but the program’s exit code will still be checked for successful completion.

Input Parameters for the Python Interface


inputstr or list

Name of input files, such as

  • a single filename (iaa012wdq_raw.fits)

  • a Python list of filenames

  • a partial filename with wildcards (\*raw.fits)

  • filename of an ASN table (\*asn.fits)

  • an at-file (@input)

outputstr, default=None

Name of the output FITS file.

dqicorrstr, optional, default=”PERFORM”

Update the dq array from bad pixel table. Allowed values are “PERFORM” and “OMIT”.

darkcorrstr, optional, default=”PERFORM”

Subtract the dark image. Allowed values are “PERFORM” and “OMIT”.

flatcorrstr, optional, default=”PERFORM”

Multiply by the flatfield image. Allowed values are “PERFORM” and “OMIT”.

shadcorrstr, optional, default=”PERFORM”

Correct for shutter shading (CCD). Allowed values are “PERFORM” and “OMIT”.
