1.0.0 (2016-03-15)

General

  • ccdproc has now the following requirements:
    • Python 2.7 or 3.4 or later.
    • astropy 1.0 or later
    • numpy 1.9 or later
    • scipy
    • astroscrappy
    • reproject

New Features

  • Add a WCS setter for CCDData. [#256]
  • Allow user to set the function used for uncertainty calculation in average_combine and median_combine. [#258]
  • Add a new keyword to ImageFileCollection.files_filtered to return the full path to a file [#275]
  • Added ccd_process for handling multiple steps. [#211]
  • CCDData.write now writes multi-extension-FITS files. The mask and uncertainty are saved as extensions if these attributes were set. The name of the extensions can be altered with the parameters hdu_mask (default extension name 'MASK') and hdu_uncertainty (default 'UNCERT'). CCDData.read can read these files and has the same optional parameters. [#302]

Other Changes and Additions

  • Issue warning if there are no FITS images in an ImageFileCollection. [#246]
  • The overscan_axis argument in subtract_overscan can now be set to None, to let subtract_overscan provide a best guess for the axis. [#263]
  • Add support for wildcard and reversed FITS style slicing. [#265]
  • When reading a FITS file with CCDData.read, if no data exists in the primary hdu, the resultant header object is a combination of the header information in the primary hdu and the first hdu with data. [#271]
  • Changed cosmicray_lacosmic to use astroscrappy for cleaning cosmic rays. [#272]
  • CCDData arithmetic with number/Quantity now preserves any existing WCS. [#278]
  • Update astropy_helpers to 1.1.1. [#287]
  • Drop support for Python 2.6. [#300]
  • The add_keyword parameter now has a default of True, to be more explicit. [#310]
  • Return name of file instead of full path in ImageFileCollection generators. [#315]

Bug Fixes

  • Adding/Subtracting a CCDData instance with a Quantity with a different unit produced wrong results. [#291]
  • The uncertainty resulting when combining CCDData will be divided by the square root of the number of combined pixel [#309]
  • Improve documentation for read/write methods on CCDData [#320]
  • Add correct path separator when returning full path from ImageFileCollection.files_filtered. [#325]

0.3.3 (2015-10-24)

New Features

  • add a sort method to ImageFileCollection [#274]

Other Changes and Additions

  • Opt in to new container-based builds on travis. [#227]
  • Update astropy_helpers to 1.0.5. [#245]

Bug Fixes

  • Ensure that creating a WCS from a header that contains list-like keywords (e.g. BLANK or HISTORY) succeeds. [#229, #231]

0.3.2 (never released)

There was no 0.3.2 release because of a packaging error.

0.3.1 (2015-05-12)

New Features

Other Changes and Additions

  • Add extensive tests to ensure ccdproc functions do not modify the input data. [#208]
  • Remove red-box warning about API stability from docs. [#210]
  • Support astropy 1.0.5, which made changes to NDData. [#242]

Bug Fixes

  • Make subtract_overscan act on a copy of the input data. [#206]
  • Overscan subtraction failed on non-square images if the overscan axis was the first index, 0. [#240, #244]

0.3.0 (2015-03-17)

New Features

  • When reading in a FITS file, the extension to be used can be specified. If it is not and there is no data in the primary extension, the first extension with data will be used.
  • Set wcs attribute when reading from a FITS file that contains WCS keywords and write WCS keywords to header when converting to an HDU. [#195]

Other Changes and Additions

  • Updated CCDData to use the new version of NDDATA in astropy v1.0. This breaks backward compatibility with earlier versions of astropy.

Bug Fixes

  • Ensure dtype of combined images matches the dtype of the Combiner object. [#189]

0.2.2 (2014-11-05)

New Features

  • Add dtype argument to ccdproc.Combiner to help control memory use [#178]

Other Changes and Additions

  • Added Changes to the docs [#183]

Bug Fixes

  • Allow the unit string "adu" to be upper or lower case in a FIS header [#182]

0.2.1 (2014-09-09)

New Features

  • Add a unit directly from BUNIT if it is available in the FITS header [#169]

Other Changes and Additions

  • Relaxed the requirements on what the metadata must be. It can be anything dict-like, e.g. an astropy.io.fits.Header, a python dict, an OrderedDict or some custom object created by the user. [#167]

Bug Fixes

  • Fixed a new-style formating issue in the logging [#170]

0.2 (2014-07-28)

  • Initial release.
