snorer.galactic_to_beta¶

snorer.galactic_to_beta(l,b,GC_coord=[0,0])¶

Transform galactic coordinate \((\ell,b)\) to off-center angle \(\beta\). See Eqs. (2) in Coordinate Transformations.

l : array_like
    Galactic longitude, rad.

b : array_like
    Galactic latitude, rad.

GC_coord : list
    Galactic coordinate for arbitrary galactic center \((\ell_g,b_g)\). Default is Milky Way center GC_coord = [0,0].

out : scalar/ndarray
    Off-center angle \(\beta\), rad. The result is scalar if all inputs are scalars.
