load_default_power

randomfield.powertools.load_default_power()

Loads a default power spectrum P(k,z) with 1e-4 <= k <= 22 and z = 0.

The default power spectrum was created using:

from randomfield.power import calculate_power
result = calculate_power(1e-4, 22.)
np.savetxt('default_power.dat', result)

The range of k values used here is sufficient to cover grids with spacing >= 0.25 Mpc/h and and box dimensions <= 50 Gpc/h.
