I propose to switch from the current Healpix C++ backend to the `ducc0` package (https://pypi.org/project/ducc0), because of the following advantages
- `ducc0`can be directly installed as a binary wh…

Currently, there is a base 12 / base 16 geohash implemented. First it determines which bin of 12 a coordinate falls in, and then the "remainder" healpix, each is converted into hex and concatenated t…

This is a feature request to add a flux-conserving (and equivalently count-conserving) reprojection method to / from HEALPIX.
For HEALPIX HEALPIX it would be trivial, just multiply / divide by 4 to …

@cdeil @fxpineau @astrofrog @tboch - Following our discussion from PyGamma19, a mid-term goal is to replace the current C HEALPix implementation from astrometry.net with [the new Rust one](https://cra…

If `from_jansky` is set in healpix_interpolate, then the convert_kelvin_jansky function is run to get the conversion scalar.

I remember @woodmd recently said something along the lines of

Hi @keewis - I was having a quick look at this package and was wondering how you generate the regridding weights? Is it just with ESMF? And then the [regridder](https://github.com/IAOCEA/xarray-healpy…
