Background Currently, astropy maintains three primary branches: The main (development) branch. The current bugfix branch (currently 5.3.x). The LTS branch (currently 5.0.x); however, the acceptance of APE21 will end this soon. For the vast majority of changes, they are PRs made against the main br...

This is a 'big picture' issue but we should in general make sure that anywhere that accepts filenames/paths in astropy can accept pathlib.Path objects. This is in the standard library and is a very convenient way of defining file paths. A lot of parts of astropy should already work with this, but as...

Description Hello ! It looks like the astropy webpage and documentation upgrade to version 5.3 did not work: main page https://www.astropy.org mention current version 5.3 and links to a whats new in version 5.2 documentation pages lands on Astropy v5.4.dev0+g2739197e6.d20230522 Expected behav...

I just noticed this but I really don't know how long this has been going on. It is pulling matplotlib 3.7.1 (stable) even though we ask it to pull from matplotlib dev in tox.ini. Example log from main: https://app.circleci.com/pipelines/github/astropy/astropy/15934/workflows/49370191-e4b0-41fd-b412-...

What is the problem this feature will solve? I have a number of (FITS) tables that use WCS to describe arrays within table cells, as described in the WCS paper section 3.1. Here basically, each column is associated with a WCS header that has a format slightly differing from the "normal" (global) one...

I see this in the predeps job that pulls in numpy 1.25rc1. Example log: https://github.com/astropy/astropy/actions/runs/5117103756/jobs/9199883166 Hard to discern between the other 100+ failures from #14881 and I do not understand why we didn't catch this earlier in devdeps. @mhvk , does this look f...

It has been fixed in HDF5 dev at h5py/h5py#2242 so we just have to wait this out. Example log: https://github.com/astropy/astropy/actions/runs/5117103756/jobs/9199883166

What is the problem this feature will solve? Currently the "astropy/table/tests/test_init_table.py" and "astropy/utils/tests/test_metadata.py" files violate Ruff rule C406, which checks for unnecessary list or tuple literals that can be rewritten as a dict literal.

What is the problem this feature will solve? Currently the "astropy/io/ascii/misc.py", and "astropy/io/ascii/tests/test_read.py" files violate Ruff rule C414, which Checks for unnecessary 'list', 'reversed', 'set', 'sorted', and 'tuple' call within list, set, sorted, and tuple calls. Describe the de...

Description I ran into an issue while using ascii.write from astropy.io.ascii to save a table in the Machine Readable Table (MRT) format. The problem arises when attempting to write the column labels, as they are not correctly identified in the resulting MRT file. Instead, the labels are displayed a...
