Description If I add a list of columns to a table with add_columns, without specifying indexes, the added columns in resulting table will have different orders from the given list. Although the order of the columns does not change much, but I would expect what I put in the table stays the same...

This is still the case with astropy 5.2.dev. Was it intentional or a design oversight? @mwcraig , do you know? >>> import numpy as np >>> from astropy import units as u >>> from astropy.nddata import CCDData, NDData >>> ndd = NDData(np.ones((10, 8))) >>>...

FITS WCS is not guaranteed to have restfrq/restwav match, which leads to unexpected behavior when transforming coordinates: >>> from astropy.wcs import WCS >>> ww = WCS(header = {'CRVAL1': 100, 'CTYPE1': 'VOPT', 'CDELT1': 1.0, 'CUNIT1': 'm/s', 'CRPIX1': 1, 'RESTFRQ': 1e9}) >>...

Workaround Use development version until v5.0.5 is released if you are stuck with v5.0.x series. Description Note: This issue is fixed in the development version of astropy. Unfortunately, the version of astropy I have to use is fixed at 5.0 and is unlikely to ever be updated, so I would like to...

Seems like scipy has some circular statistics support that might overlap with astropy a little. However, API is not exactly the same and I am not sure if both sides cover all the same use cases. There is a need to do the following: Compare https://docs.astropy.org/en/latest/stats/circ.html with htt...

Description In processing an extremely large amount of data, my code attempts to create a fits.Column object from that data which fails in a numpy call made by astropy.io.fits. A simplified reproducer of the issue is import numpy as np from astropy.io import fits dat = np.zeros(2150000000) fmt...

Description Reading existing fits files with units of milli-bar fails now with astropy 5.x (not sure exactly when this happened): In [5]: u.Unit("mbar", format="fits") --------------------------------------------------------------------------- ValueError Traceback...

Right now we use a small subset of flake8 in pre-commit. Given that pre-commit runs primarily on PR diffs, it seems fine to check for more problems. There are hundreds of violations of the full flake8 checks, so I think we should sequentially add codes to pre-commit to keep correction PRs small (the...

https://docs.astropy.org/en/latest/development/workflow/virtual_pythons.html We should encourage the use of Miniconda over Anaconda. We do not want user to get bloated base env before they even start doing dev work on astropy. Replace Anaconda with Miniconda. Maybe even add a note to discourage the...
