error in compute_celestial_positions function

[pixel70]

function compute_celestial_positions contains the line

• 22438.42 * np.cos(l_prime-f_omega_d)

where f_omega_d = 2 * (F + omega - D)

But I think the line should be

• 22438.42 * np.cos(l_prime+f_omega_d)

because IERS table 5.2b says

i b_{s,j})i b{c,j})_i l l' F D Om
