$NTFFparameter

Format

$NTFFparameter
 Intype    fi    ff    N                
   θi      θf    Nθ
   φi      φf    Nφ                // Intype, N, Nθ, and Nφ are integers, the others are floating points.

Intype: 1 means f_i and f_f are frequencies; on the other hand, 2 means they are wavelengths.
f_i: initial frequency or wavelength.
f_f: final frequency or wavelength.
N: the number of frequencies between f_i and f_f.

θ_i: initial θ.
θ_i: final θ.
N_θ: the number of θ you want to compute between θ_i and θ_f.

φ_i: initial φ.
φ_i: final φ.
N_φ: the number of φ you want to compute between φ_i and φ_f.

Note: the function -- $NTFFposition -- also must be used.
