Look-up table
Look-up table is generated in method make_lookup_table called as
lut = make_lookup_table(b1, b2, b3, hmax, kmax, lmax, np.float32, evald_rad, sigma_q, fout, bpq, bpomega, bpbeta)
for each crystal orientation in omega_deg and beta_deg method
dr, qv, qh = radial_distance(xrot2, yrot1, zrot2, evald_rad)
evaluates
dr [1/A] - distance between lattice node and Evald's sphere
qv, qh [1/A] - vertical and horizontal components of scattering vector q
in a simple code:

def radial_distance(X, Y, Z, evald_rad=0.5) :
DX = X + evald_rad
L = np.sqrt(DX*DX + Y*Y + Z*Z)
dr = L - evald_rad
qv = evald_rad * Z/L
ql = evald_rad * (DX/L-1)
qy = evald_rad * Y/L
qh = np.sqrt(ql*ql + qy*qy) * np.select([Y<0], [-1], default=1)
return dr, qv, qh |
Finally, in method make_lookup_table
txt = str_omega_drhkl(ind, beta_deg, omega_deg, dr, r, qv, qh, h, k, l, sigma_q)
generates text record for file with look-up table, and
lut[iomega,:] += fill_row(dr, qv, qh, h, k, l, sigma_q, bpq)
generates 2-d array, which presents look-up table in plot.
