SphericalProj.ang2xy(theta, phi=None, lonlat=False, direct=False)

From angular direction to position in the projection plane (%s).

  • theta: if phi is None, theta[0] contains theta, theta[1] contains phi
  • phi : if phi is not None, theta,phi are direction
  • lonlat: if True, angle are assumed in degree, and longitude, latitude
  • flipconv is either ‘astro’ or ‘geo’. None will be default.
  • x, y: position in %s plane.
