I'm running this on with Pixell.jl on the alm2map branch. I need to find time to write some unit tests before I merge that branch to master. Benchmark results are on a 16-core AMD EPYC.
using Pixell, BenchmarkTools, Tullio
using Pixell: degree, arcminute # not exported by default
## let's make up a big patch similar to ACT DR6 / SO view of the southern sky
box = [180 -180; # RA
-70 30] * degree # DEC
shape, wcs = geometry(CarClenshawCurtis, box, 8 * arcminute) # note: 8x downgraded from native ACT/SO maps
