Add a context manager for imposing a solar-radius value

1

This PR adds a context manager as an option for dealing with the situation of inconsistent values for the solar radius. This context manager makes it so that the `rsun`...

There is very old code (from #1432) that sets the `norm` to `None` for maps with 8-bit unsigned integer data (uint8, i.e., 0 to 255): https://github.com/sunpy/sunpy/blob/5bffcc28214dcfe1b4d40e811cacc6807243175a/sunpy/map/mapbase.py#L236-L237 Presumably this is done...

Provide a planar screen as an optional assumption for handling off-disk helioprojective coordinates

4

Expanding beyond `assume_spherical_screen()` (see #4003), this PR adds a planar screen as an optional assumption for handling off-disk helioprojective coordinates.  See also #6411

HMI FITS headers may not have accurate observer coordinates

3

HMI FITS headers appear to have only heliographic Carrington (HGC) coordinates for the observer (SDO). These appear to correspond very closely with the HGC coordinates in AIA FITS headers at...

`GenericMap.draw_contours()`: don't run internal transform code if `transform` keyword is provided

3

#5398 fixed some issues in `GenericMap.draw_contours()` by internally transforming the map to the axes WCS if the map WCS was different. However, we should run this code only if the...

For a coordinate with an observer, there is no requirement that the `obstime` for the observer location be the same as the `obstime` for coordinate. However, due to the quirkiness...

The `propagate_with_solar_surface()` context manager can be used to account for solar differential rotation when reprojecting a map to a different observation time, but off-disk data are discarded. The `assume_spherical_screen()` context...

FLOAT_CMP isn't powerful enough to handle whitespace that is added in fixed-width printing of floats

5

See title. Here's a minimal example with `ndarray`, where I vary the least significant digit of the element the first row: ```python >>> import numpy as np >>> np.array([[0.12345678], [0.11111111]])...

Add a list of our papers

7

We should list all of our SunPy papers somewhere. This is not a duplicate of #339, which is about papers that use SunPy. * https://ui.adsabs.harvard.edu/abs/2015CS%26D....8a4009S/abstract * https://ui.adsabs.harvard.edu/#abs/2020JOSS....5.1832M/abstract * https://ui.adsabs.harvard.edu/#abs/2020ApJ...890...68S/abstract *...

Add a Map method to draw the extent of the map

2

It's a common need to plot the extent of one map (e.g., the FOV of an instrument) onto a different WCSAxes (e.g., an image from a different instrument). One can...
