Detailed Description

HEALPix-based sky map pixelization.

We put a Tract at the position of each HEALPixel.


Parameters
----------
config : `lsst.skymap.BaseSkyMapConfig`
    The configuration for this SkyMap.
version : `int` or `tuple` of `int` (optional)
    Software version of this class, to retain compatibility with old
    instances.
