PHA data that are read in from such a file no longer renumber the CHANNEL column to start at 0 rather than 1, which will mean that notice and ignore filter ranges that are given in channel units will need to be reduced by 1. #2120 - Improve handling of STAT/SYS_ERR PHA columns Improve handling of STAT_ERR and SYS_ERR PHA columns which are set to 0. #2121 - UI: add calc_model/source commands Add calc_model and calc_source routines to return the model expression evaluated per bin. #2123 - Data cleanups Internal clean up of some of the data code. #2125 - Allow per plot kwargs for plot_xxx_components calls Allow per-plot keyword arguments for plot_model_components and plot_source_components. #2126 - Allow plot and contour to change the plot layout and have per-plot settings. Expand the plot and contour commands to allow per-plot options to be given, matching the plot_model_components/plot_source_components commands. #2129 - Fix plot overplot Improve the behaviour of plot() and contour() when called with overplot=True or overcontour=True respectively. Fix #2128. #2130 - data: fixup numpy import Fix up several typing annotations from a recent refactoring. #2133 - UI: add format and delim arguments to get_filter. Allow the get_filter call to override the format and delim arguments. Fix #1277 #2135 - Tests: tweak tolerances for macOS ARM #2135 Updated macOS ARM test tolerances #2137 - Fix doctests in sherpa.plot.__init__ Changed documentation to match backends as objects instead of modules #2138 - UI: add documentation for table to show_xsabund The show_xsabund command now includes a description of the abundance table. #2139 - Update helpdesk URL Changed helpdesk link - fixes issue #1931 #2140 - Updated docs for asymmetric errors Expanded documentation for load_ascii_with_errors to clarify assumptions for elo and ehi settings. #2141 - Update LaTeX labels and docs for bokeh Correctly render LaTeX labels in bokeh #2144 - Fix xspec missing doc Add get_xsabund_doc to the list of functions in the documentation. There is no functional change. #2147 - Improve corner-case handling of filtering and empty data handling A clean-up pass for the data classes, in particular DataPHA, to normalize the filtering and handling of an empty object #2151 - updating Sherpa citations Added a citation to the most recent sherpa paper #2152 - DATA: clean up DataPHA.get_x Internal clean up of the DataPHA.get_x method. #2153 - updated the front page of Sherpa RTD with references Added references to three sherpa papers in the sherpa docs #2154 - Update README Added additional text regarding acknowledging/citing sherpa #2155 - Drop support for Python 3.9 and add 3.12 Drop support for Python 3.9 and numpy < 1.24 and note Python 3.12 experimental support. #2157 - Improve test coverage of ignore_bad Add more corner-case of quality channel handling for PHA data. There is no functional change here. #2160 - Fixup test failures from #2118 Fix up a test case when writing out the range of a FITS column. #2161 - UI: note when a 1D filter command has failed Provide more information for the UI user if a filter command has failed. #2162 - TEST: ignore fork deprecation warnings Ignore the deprecation warnings about the use of the fork method for multiprocessing. #2177 - Read the Docs build failures with newer sphinx versions and sphinx_rtd_theme deprecation warning Specify sphinx < 8 for the read the doc environment and remove the call to get_html_theme_path no longer needed." /> <link rel="alternate" type="application/zip" href="https://zenodo.org/records/13909532/files/sherpa/sherpa-4.17.0.zip"> <link rel="item" type="application/zip"
