MollweideProj.xy2ang(x, y=None, lonlat=False, direct=False)

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

  • x : if y is None, x[0], x[1] define the position in Mollweide plane.
  • y : if defined, x,y define the position in projection plane.
  • lonlat: if True, angle are assumed in degree, and longitude, latitude
  • flipconv is either ‘astro’ or ‘geo’. None will be default.
  • theta, phi : angular direction.
