Original Changelog#

This is the original changelog from kbarbary/sep, copied here for posterity.

v1.2.1 (1 June 2022)#

  • Same as v1.2.0 but with new wheels for Python 3.10 and AArch64.

v1.2.0 (1 May 2021)#

  • Changed numpy.float and numpy.int types for deprecations in numpy 1.20 (#96).

  • Make it possible to safely invoke C library from multiple threads on independent inputs.

    Global config functions such as set_sub_object_limit() and set_extract_pixstack() still configure global params (once for all threads), while other functions will retain their data in thread-local storages, so they can be invoked from multiple threads as long as they work on independent structures.

    Library compilation will now require a C11 compatible compiler, which should be nowadays available on all supported platforms.

  • Mark some pointer parameters with const *. This is a backward-compatible change, but makes it easier to extract constants that can be safely shared between multiple threads and/or invocations.

v1.1.1 (6 January 2021)#

  • Same as v1.1.0 but with wheels built and uploaded to PyPI. Please report if you have problems with wheels.

v1.1.0 (3 January 2021)#

  • Add segmentation masking to the photometry and kron/auto functions (#69).

  • Add functions sep.set_sub_object_limit(limit) and sep.get_sub_object_limit() for modifying and retrieving the sub-object deblending limit. Previously this parameter was hard-coded to 1024. 1024 is now the default value.

  • This and future versions are now Python 3 only. Python 2 is no longer supported.

  • Modernize setup.py with pyproject.toml

v1.0.3 (12 June 2018)#

  • Fix double-free bug in sep_extract() arising when an error status occurs and convolution is on. (#56)

  • Work around numpy dependency in setup. (#59)

v1.0.2 (19 September 2017)#

  • Fix makefile so that make install works on OS X for the C library. Python module and C code are unchanged.

v1.0.1 (10 July 2017)#

  • Fix bug when using masked filter and noise array where objects with member pixels at end of image (maximum y coordinate) were erroneously missed.

v1.0.0 (30 September 2016)#

  • Remove features deprecated in previous versions.

  • Fix bug in Background.rms() giving nonsensical results.

v0.6.0 (25 August 2016)#

  • New, more coherent C API. This change should be transparent to users of the Python module.

  • Add variance uncertainty parameters errx2, erry2 and errxy to output of sep.extract().

  • Add a minimum sigma to sep.winpos() to match Source Extractor behavior.

  • Fix use of boolean masks in sep.kron_radius(). Formerly, using a boolean mask resulted in nonsense results.

  • Fix segfault in Background.back() when box size is same as image size.

  • Fix bug in creating long error messages on Python 3.

v0.5.2 (4 January 2016)#

Adds OS X and Windows support.

v0.5.1 (30 November 2015)#

Bugfix release for problem in setup.py in packaged code.

v0.5.0 (22 November 2015)#

  • sep.extract() now uses a more correct matched filter algorithm in the presence of a noise array, rather than simple convolution. The conv keyword has been changed to filter_kernel to reflect this, and a filter_type keyword has been added to allow selecting the old behavior of simple convolution.

  • sep.extract() now accepts a mask keyword argument.

  • sep.extract() can now return a segmentation map.

  • Special methods added to allow data - bkg and np.array(bkg) where bkg is a Background object.

v0.4.1 (10 November 2015)#

Bugfix release, fixing error estimate in sep.sum_circle and sep.sum_ellipse when bkgann keyword argument is given.

v0.4.0 (1 June 2015)#

  • New sep.winpos() function.

v0.3.0 (23 February 2015)#

  • New sep.flux_radius() function.

v0.2.0 (13 December 2014)#

  • [breaking change] theta field in extract() output is now in radians rather than degrees, for compatibility with new ellipse aperture functions.

  • [deprecation] Change mask_ellipse() parameters from ellipse coefficients to ellipse axes and position angle, to match aperture functions. (Old behavior still works as well.)

  • [deprecation] Change apercirc() to sum_circle(), to match new aperture functions. (Old name, apercirc(), still works.)

  • Add sum_circann(), sum_ellipse(), sum_ellipann(), kron_radius(), ellipse_coeffs(), ellipse_axes() functions.

  • Exact mode aperture photometery in all functions, with subpix=0.

  • Enable variable thresholding in sep.extract. [#11]

  • Fix bug in background masking. This bug impacted masking in all functions that used masking. Also affected C library.

  • More detail in error messages coming from within the C library. More helpful error message for non-native byteorder arrays.

  • Add ability to change pixel stack size used in extract(), with set_extract_pixstack() function

v0.1.0 (11 August 2014)#

This is the first official release.
