Hello Andreas,

please see this as a side remark.

A colleague of mine made me aware of a very beautiful thing about
covering spheres by evenly spaced points:

Since you want to calculate mean and stddev, to my understanding a
grid in longitude/latitude is without proper weighting factors
problematic.  Do you use weighting factors?  If yes, of what kind?

For Healpix, there exists exists a Python binding, but I never worked with it.

Friedrich
