ccdproc 2.0.1

2.0.1 fixes a bug that required pytest to be installed to import ccdproc.

Release notes from 2.0:

This is the first release of ccdproc that is Python 3 only!

New and improved

The ImageFileCollection for working with sets of images has several new features:

• Construct a collection from an explicit list of files.
• Filter files using regular expression matching.
• Create a new collection by filtering an existing collection.

Other new features include:

• Weights in image combination can be a 1D array.
• Reduced memory in image combination.
• Many fewer files open during image combination when using memory mapping and breaking the image stack into chunks.
• Better performance and a wider array of compression types for ImageFileCollection.
• Better handling of constructing error array when some image value are negative.

In addition, several bugs were fixed.

See the changelog for more details.

v1.3.0.post1

Changed released package on PyPI to tar.gz without Windows line-endings

v1.3.0

New Features

• Add representation for ImageFileCollection. [#475, #515]

• Added ext parameter and property to ImageFileCollection to specify the FITS
  extension. [#463]

• Add keywords.deleter method to ImageFileCollection. [#474]

• Added glob_include and glob_exclude parameter to
  ImageFileCollection. [#484]

• Add bitfield_to_boolean_mask function to convert a bitfield to a
  boolean mask (following the numpy conventions). [#460]

• Added gain_corrected option in ccd_process so that calibration
  files do not need to previously been gain corrected. [#491]

• Add a new wcs_relax argument to CCDData.to_header() that is passed
  through to the WCS method of the same name to allow more flexible
  handing of headers with SIP distortion. [#501]

• combine now accepts numpy.ndarray as the input img_list.
  [#493, #503]

• Added sum option in method for combime. [#500, #508]

• Add norm_value argument to flat_correct that allows the normalization
  of the flat frame to be manually specified. [#584, #577]

Other Changes and Additions

• removed ability to set unit of CCDData to None. [#451]

• deprecated summary_info property of ImageFileCollection now raises
  a deprecation warning. [#486]

• Logging will include the abbreviation even if the meta attribute of
  the processed CCDData isn't a fits.Header. [#528]

• The CCDData class and the functions fits_ccddata_reader and
  fits_ccddata_writer will be imported from astropy.nddata if
  astropy >= 2.0 is installed (instead of the one defined in ccdproc). [#528]

• Building the documentation requires astropy >= 2.0. [#528]

• When reading a CCDData from a file the WCS-related keywords are removed
  from the header. [#568]

• The info_file argument for ImageFileCollection is now deprecated.
  [#585]

Bug Fixes

• ImageFileCollection now handles Headers with duplicated keywords
  (other than COMMENT and HISTORY) by ignoring all but the first. [#467]

• The ccd method of ImageFileCollection will raise an
  NotImplementedError in case the parameter overwrite=True or
  clobber=True is used instead of silently ignoring the parameter. [#527]

• The sort method of ImageFileCollection now requires an explicitly
  given keys argument. [#534]

• Fixed a problem with CCDData.read when the extension wasn't given and the
  primary HDU contained no data but another HDU did. In that case the header
  were not correctly combined. [#541]

• Suppress errors during WCS creation in CCDData.read(). [#552]

• The generator methods in ImageFileCollection now don't leave open file
  handles in case the iterator wasn't advanced or an exception was raised
  either inside the method itself or during the loop. [#553]

• Allow non-string columns when filtering an ImageFileCollection with a
  string value. [#567]
