Test docs build with Sphinx fork that fixes the inheritance-diagram links

2

This is a test PR to confirm that the pending Sphinx PR (sphinx-doc/sphinx#10576) to fix the bug with links in inheritance diagrams does in fact fix the issue in Astropy's...

LASCO FITS headers do not have observer location

4

Apparently the LASCO FITS headers do not have the location of the spacecraft (e.g., `HGLN_OBS`, `HGLT_OBS`). When such information is missing, our software assumes that the observer is at Earth,...

Should SunPy use memory mapping for access to files?

7

By default, Astropy opens FITS files using memory mapping (or rather, [it tries to](https://github.com/sunpy/sunpy/issues/1745#issuecomment-310935318)). That is, the returned `ndarray` objects have `mmap` objects as their ultimate base of storage, and...

As [noted on the mailing list](https://groups.google.com/d/msgid/sunpy/0352a093-e23d-4681-8113-e560bd2be92an%40googlegroups.com), the calculation in the header helper of a PCij matrix from a rotation angle is incorrect when working with rectangular pixels (`CDELT1` not equal...

Bug prevents `RotatedSunFrame` instances from being pickled

5

I haven't actually confirmed this, but I presume that the bug that prevents `SkyOffsetFrame` instances from pickled (astropy/astropy#9249) also means that `RotatedSunFrame` instances can't be pickled. We should incorporate the...

#5867 provided other packages and users the ability to add a rotation function for use by `affine_transform()` and `GenericMap.rotate()`. However, the list of available rotation functions in the docstrings for...

Remove authorship information from the code itself?

15

Let's have a discussion about whether to remove authorship information from the code itself (e.g., `__author__` and `__email__`). (See [triggering comment thread](https://github.com/sunpy/sunpy/pull/3646#discussion_r363508066).) Some reasons to remove it: - It's not...

See #2097 for context DO NOT MERGE

If you provide `GenericMap.submap()` with a coordinate frame with data (i.e., derived from `BaseCoordinateFrame`) rather than an actual `SkyCoord` instance, it errors when it doesn't need to: ```python >>> import...

Add the option to automatically determine the extent of a map when using `reproject_to()`

5

Based on a discussion on Element and the proof of concept [here](https://colab.research.google.com/drive/1NU3ooz8KNt8zURcrQDKr-yyxTzY_j8CH?usp=sharing), it'd be neat to have the option for `GenericMap.reproject_to()` to automatically determine the extent of the reprojected map....
