Reduction Reference

Below is a list of all functions that are part of the reduction module, grouped by filename.

• preproc.py - preprocessing functions.

  • choose_calib - calibration images visualization and selection.
  • choose_science - display science images for verification by user.
  • mkmaster - make master calibration frames (bias, dark, flat).

• autoproc.py - automated pipeline script.

  • autoproc - main function.

• autoproc_steps.py - reduction processing steps.

  • autopipedefaults - set commonly used variables to use throughout each step.
  • autopipeprepare - update image headers and performs bias/dark subtraction.
  • autopipeimflatten - flatten data using flat with matching filter name.
  • autopipemakesky - combine sky flats based on filter type (sigma clipping for sources).
  • autopipeskysub - subtract both master sky and median.
  • autopipeskysubmed - subtract median, does NOT use master sky.
  • autopipecrcleanim - remove cosmic rays.
  • autopipeastrometry - calculate astrometry of image files to fix WCS coordinates.
