◆ angToCoord()

lsst.skymap.healpixSkyMap.angToCoord ( thetaphi)
Convert hpgeom ang to an lsst.geom.SpherePoint

The angle is provided as a single object, thetaphi, so the output
of hpgeom functions can be directed to this function without
additional translation.

Definition at line 40 of file healpixSkyMap.py.

◆ coordToAng()

lsst.skymap.healpixSkyMap.coordToAng ( coord)
Convert an lsst.geom.SpherePoint to a hpgeom ang (theta, phi)

The Healpix convention is that 0 <= theta <= pi, 0 <= phi < 2pi.
