astropy v2.0.9 Release Notes

Release Date: 2018-10-14 // over 5 years ago

  • 🐛 Bug Fixes

    astropy.io.ascii ^

    • 🛠 Fix reading of big files with the fast reader. [#7885]

    astropy.io.fits ^

    • HDUList.__contains__() now works with HDU arguments. That is, hdulist[0] in hdulist now works as expected. [#7282]

    • HDUList s can now be written to streams in Python 3 [#7850]

    astropy.nddata ^

    • 🛠 Fixed the bug in CCData.read when the HDU is not specified and the first one is empty so the function searches for the first HDU with data which may not have an image extension. [#7739]

    astropy.stats ^

    • 🛠 Fixed bugs in biweight statistics functions where a constant data array (or if using the axis keyword, constant along an axis) would return NaN. [#7737]

    astropy.table ^

    • 🛠 Fixed a bug in to_pandas() where integer type masked columns were always getting converted to float. This could cause loss of precision. Now this only occurs if there are actually masked data values, in which case pandas does require the values to be float so that NaN can be used to mark the masked values. [#7741, #7747]

    ✅ astropy.tests ^

    • 🔄 Change the name of the configuration variable controlling the location of the Astropy cache in the Pytest plugin from cache_dir to astropy_cache_dir. The command line flag also changed to --astropy-cache-dir. This prevents a conflict with the cache_dir variable provided by pytest itself. Also made similar change to config_dir option as a precaution. [#7721]

    astropy.units ^

    • UnrecognizedUnit instances can now be compared to any other object without raising TypeError. [#7606]

    astropy.visualization

    • 🛠 Fix compatibility with Matplotlib 3.0. [#7839]

    • 🛠 Fix an issue that caused a crash when using WCSAxes with a custom Transform object and when using grid_type='contours' to plot a grid. [#7846]

    astropy.wcs ^

    • Instead of raising an error astropy.wcs now returns the input when the input has zero size. [#7746]

    • Fix malloc(0) bug in pipeline_all_pixel2world() and pipeline_pix2foc(). They now raise an exception for input with zero coordinates, i.e. shape = (0, n). [#7806]

    • 🛠 Fixed an issue with scalar input when WCS.naxis is one. [#7858]

    Other Changes and Additions

    • Added a new astropy.__citation__ attribute which gives a citation for Astropy in bibtex format. Made sure that both this and astropy.__bibtex__ works outside the source environment, too. [#7718]
