Usage

import lumfunc as lf
import numpy as np

lf.get_maggy(np.array([10, 100, 20])) # returns maggy values

get_maggy( )

Converts magnitudes into maggies.

lf.get_maggy(np.array([10, 100, 20])) 
# returns array([1.e-04, 1.e-40, 1.e-08])

get_patches( )

Divides survey into equally distributed and equally sized patches. Returns labels for patches from RA, Dec, number of patches and patch center guesses.

lf.get_patches(np.array([20, 21, 22, 20, 21, 22]),
            np.array([20, 21, 22, 20, 21, 22]),
            3,
            np.array([[20, 21], [22, 20], [21, 22], [20, 21], [22, 20],
                      [21, 22]]),
            survey='kids',
