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 the field of view in degree of the plane of projection
`ij2xy`([i, j])	From image array indices to position in projection plane (Cartesian).
`projmap`(map, vec2pix_func[, rot, coord])	Create an array containing the projection of the map.
`set_flip`(flipconv)	flipconv is either ‘astro’ or ‘geo’.
`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).
