Code given to Ryan for basic az integrations:

def radial_profile(data, center=None):
    if center is None:
        center = (data.shape[0] // 2, data.shape[1] // 2)    
    y, x = np.indices(data.shape)
    r = np.sqrt((x - center[1])**2 + (y - center[0])**2)
    r = r.astype(int)    
    tbin = np.bincount(r.ravel(), data.ravel())
    nr = np.bincount(r.ravel())
    radialprofile = tbin / nr   
    return radialprofile
