healpy.projector.CartesianProj.projmap¶
- CartesianProj.projmap(map, vec2pix_func, rot=None, coord=None)¶
Create an array containing the projection of the map.
- Input:
vec2pix_func: a function taking theta,phi and returning pixel number
- map: an array containing the spherical map to project,
the pixelisation is described by vec2pix_func
- Return:
a 2D array with the projection of the map.
Note: the Projector must contain information on the array.
