Attributes
arrayinfo
Dictionary with information on the projection array Methods
ang2xy
(theta[, phi, lonlat, direct])From angular direction to position in the projection plane (Cartesian). get_center
([lonlat])Get the center of the projection. get_extent
()Get the extension of the projection plane. get_fov
()get_proj_plane_info
()ij2xy
([i, j])From image array indices to position in projection plane (Cartesian). mkcoord
(coord)projmap
(map, vec2pix_func[, rot, coord])Create an array containing the projection of the map. set_flip
(flipconv)flipconv is either ‘astro’ or ‘geo’. None will be default. set_proj_plane_info
(xsize, ysize, lonra, latra)vec2xy
(vx[, vy, vz, direct])From unit vector direction to position in the projection plane (Cartesian). xy2ang
(x[, y, lonlat, direct])From position in the projection plane to angular direction (Cartesian). xy2ij
(x[, y])From position in the projection plane to image array index (Cartesian). xy2vec
(x[, y, direct])From position in the projection plane to unit vector direction (Cartesian).
