-    A class to transform cosmology distance to angles or pixels.
-
-    Parameters
-    ------------
-    H0: float
-        The hubble constant at z = 0, whose unit is km/s/Mpc
-    Om0: float
-        The total matter density.
-    ang_res: float
-        Angular resolution, i.e. degree per pixel. (May be useless)
-    ang_total: list
-        Total angles of the simulated sky region, whose unit is degree
-    z : float
-        Redshift
-    scale: float
-        The real object scale.
