Dictionary with information on the projection array
Methods
ang2xy
(self, theta[, phi, lonlat, direct])From angular direction to position in the projection plane (Cartesian).
get_center
(self[, lonlat])Get the center of the projection.
get_extent
(self)Get the extension of the projection plane.
get_fov
(self)Get the field of view in degree of the plane of projection
ij2xy
(self[, i, j])From image array indices to position in projection plane (Cartesian).
projmap
(self, map, vec2pix_func[, rot, coord])Create an array containing the projection of the map.
set_flip
(self, flipconv)flipconv is either ‘astro’ or ‘geo’.
