Numpy 2.0 will "clean up" the Python API (and change the C API)

9

Numpy plans a release candidate for numpy 2.0 late in Dec 2023 with significant clean-up of the Python API and changes to the C API: https://github.com/numpy/numpy/issues/24300 There is almost certainly...

APE0: Coco term limits and Ombudsperson

19

I want to suggest several changes to APE0. They touch different aspects of Astropy governance and should be voted on separately by the members. However, for the purpose of a...

2D data looks crazy - is it mixing up x0/x1 in some cases?

5

This issue has a title that's intentionally similar to #840. However, while #840 is about regridding, here, I see things that look like crazy mixups even without regridding. ```Python import...

Inconsistent naming for axis between 2D models and 2D data

1

In the data objects, the independent axes are called `x0` and `x1` and the *dependent* coordinate is called `y`, e.g. ```Python DataIMGInt("binned_image", ... x0lo=x0lo.flatten(), x1lo=x1lo.flatten(), ... x0hi=x0hi.flatten(), x1hi=x1hi.flatten(), ... y=hist.flatten())...

Can we improve error messages in UI by listing the dataset ids that cause error?

1

## Why am I annoyed? Here is my sherpa session from today: ```Python from sherpa.astro import ui ui.load_pha("../data/default/P0502370201R1S001SRSPEC1001.FIT") # do some other stuff like find the RMF on the files...

Astropy has two bibtex entries, which unfortunately get displayed without newlines under "bibtex".

Add an explicit code on conduct specific to this project

2

This is a fairly standard software project doe of conduct that's been adopted by many projects in the community. I reviewed the SAO, CfA, and MIT specific codes, but they...

Add a security reporting policy

3

This text assumes that someone with "admin" permission in the repro (probably Warren?) activates github private security reporting, which wont' hurt: https://docs.github.com/en/code-security/security-advisories/working-with-repository-security-advisories/configuring-private-vulnerability-reporting-for-a-repository If that form is activated, all repro admins...

In a few places (e.g. https://github.com/sherpa/sherpa/pull/2025#discussion_r1590433818) Sherpa still uses numpy's old "matrix" class, which is almost, but not entirely identical to the normal ndarray. `matrix` is no longer recommended and...

Re-implement XSPEC models for partical covering, redshift, etc. in Sherpa?

2

Benchmarking indicates that, for the a typical use case of fitting X-ray spectra with XSPEC models, Sherpa spends >95% of the time in the binary XSPEC code to evaluate XSPEC...
