Note

ccdproc works only with astropy version 2.0 or later.

The ccdproc package provides:

  • An image class, CCDData, that includes an uncertainty for the data, units and methods for performing arithmetic with images including the propagation of uncertainties.
  • A set of functions performing common CCD data reduction steps (e.g. dark subtraction, flat field correction) with a flexible mechanism for logging reduction steps in the image metadata.
  • A function for reprojecting an image onto another WCS, useful for stacking science images. The actual reprojection is done by the reproject package.
  • A class for combining and/or clipping images, Combiner, and associated functions.
  • A class, ImageFileCollection, for working with a directory of images.
