Module: radial_distributions

equal_area_annuli(R, N, i=None)

provides the radius r[i] for N concentric annular regions in such a way that each annular region surface s[i]=pi*(r[i]**2-r[i-1]**2)=pi*R**2/N

Args:

R (float): the outern radius N (int): the total number of annular regions i (int) or array of (int): the index for the annular region or the array of indices

Returns:

r (float): the radius r[i] (if is scalar) or the the full array r if i is an array
