Release 1.0.3

• Fix to properly display Python error message that may occur in the user python configuration
• Build packages for Fedora 42

1.0.2 Hotfix

Hotfix release to fix a regression when using Assoc mode in no detection image mode

Release 1.0.1

Fix compilation of deprecated boost call on recent versions

Release 1.0

What's Changed

• Configurable model fitting window shapes
• Renormalization of the model fitting PSF can be toggled on or off (psf_renormalize parameter to MesaurementImage (default True)
• Allow specifying a reference image to be used when working without a detection image. (Previously the first measurement image was always used.) New command line parameter: --reference-image

Requirements

Alexandria 2.31.4 Elements 6.3.3

0.22.2 maintenance release

fix for a bug in quadtree causing moffat grouping crash

0.22

SourceXtractor++ 0.22

Changes:

• Grouping stage performance optimization. Grouping should be much faster when there is a large number of detected sources.
• Now using a fixed random generator seed for more deterministic output (can be set with --rng-seed)
• Model fitting now outputs fitting rectangle size
• Aperture photometry can now work without a detection image
• Now correctly disable partition steps when running without a detection image
• Fixed cryptic errors when running SourceXtractor++ without parameters
• Fixed incorrect check images (filtered, thresholded and snr)

Dependencies: Alexandria 2.31.0, Elements 6.2.3

0.21

Release 0.21
(Note: there is no version 0.20 on github as that was used for an internal release)

• Can now work without a detection image by supplying an assoc catalog
• Added check images for measurement images background (--check-image-measurement-background and --check-image-measurement-variance)

Important bug fixes:

• iterative model fitting was using the current value of parameters for the range instead of initial value.
• WCS tranform errors are caught and display a warning instead of stopping everything
• fixes problems with BLAS multithreading

Dependencies: Alexandria 2.31.0, Elements 6.2.3

2024-01-10: Conda packages now available.

0.19.2 Hotfix release

Fixes the numerical precision issues with position (see #533)

0.19 Release

Requirements: Alexandria 2.27.0, Elements 6.0.1

New in 0.19:

• Support for FITS Data cubes
• Columns from ASSOC catalogs can be used in mode fitting configuration
• Changes in some command line parameters (see below)
• Many bug fixes and internal enhancements

Details:

Several command line parameters have been modified to make their behavior more clear:
use-cleaning, use-attractors-partition, partition-corethreshold become booleans, so instead of --use-cleaning' you have to write use-cleaning=true' this makes their behavior consistent between command line and configuration file use.

Also since it would have caused double negatives, the following parameters have also been renamed :
segmentation-disable-filtering becomes the boolean segmentation-use-filtering (on by default)
output-flush-unsorted becomes the boolean output-flush-sorted (on by default)
progress-bar-disable becomes the boolean progress-bar (on by default)

How to use the new FITS cubes:
g1 = load_fits_data_cube('cube.fits', sorted(glob('sim11_g_??.psf')))

to load individual slices:
DataCubeSlice('cube.fits', "nopsf", image_layer=3)

0.18 release

• Added support for assoc mode using world coordinates
• Added support for assoc and MEF detection images
• Fixed a race condition
• Updated the documentation
