This is a release of mwa_hyperbeam, primary beam code for the MWA, obtained
from the GitHub releases
page.
hyperbeam is licensed under the Mozilla Public License 2.0 (MPL
2.0). The LICENSE file is the relevant
copy.
Other licenses are included from the hdf5 (COPYING-hdf5) and erfa
(LICENSE-erfa) libraries. These are included because (as per the terms of the
licenses) hdf5 and erfa are compiled inside the hyperbeam products in this
tarball.
They are microarchitecture levels. By default, Rust compiles for all x86-64 CPUs; this allows maximum compatibility, but potentially limits the runtime performance because many modern CPU features can't be used. Compiling at different levels allows the code to be optimised for different classes of CPUs so users can get something that works best for them.
You're probably safe with x86-64-v2, especially if your CPU was made after 2010. If your CPU is older than that, you may want x86-64. If your CPU is a little newer, x86-64-v3 is also likely to work. x86-64-v4 isn't widely supported (AVX-512), so only use that if you know it works.
