Can I use healpy to stack sky?

I would like to stack WMAP maps at the locations of galaxies. Is it possible to perform this using healpy? Which function in healpy allows me to get a projection of the sky around a point? thanks

with gnomview you can specify the central point with rot, then set return_projected_map=True to get a 2D array of the projected map back.
