Hello,

I want to compute forward and inverse spherical harmonic transforms in Julia. I tried using FastTransforms but the package appears to be unstable (on the Mac Desktop, at any rate) and I also can’t seem to control parameters of the transform such as the harmonic bandlimit. Furthermore, I’m unable to determine the data format, i.e. the order of coefficients and how to arrange the latitudes / longitudes. Could someone please point me to documentation / examples?

Thanks a lot.
