healpy.projector.GnomonicProj¶
- class healpy.projector.GnomonicProj(rot=None, coord=None, xsize=None, ysize=None, reso=None, **kwds)¶
This class provides class methods for Gnomonic projection.
Methods
ang2xy(theta[, phi, lonlat, direct]) From angular direction to position in the projection plane (Gnomonic). get_center([lonlat]) Get the center of the projection. get_extent() get_fov() get_proj_plane_info() ij2xy([i, j]) From image array indices to position in projection plane (Gnomonic). 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, reso]) vec2xy(vx[, vy, vz, direct]) From angular direction to position in the projection plane (Gnomonic). xy2ang(x[, y, lonlat, direct]) From position in the projection plane to angular direction (Gnomonic). xy2ij(x[, y]) From position in the projection plane to image array index (Gnomonic). xy2vec(x[, y, direct]) From position in the projection plane to unit vector direction (Gnomonic).
