This class provides class methods for Cartesian projection.

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).
