**_af**= frequency axis for FPI data

**_coq**= interpolation to constant q

**_mph**= multiphonon correction for DOS

**_muc**= DOS calculation on basis of MUPHCOR

**_pm**= +- convention for energies

**_sac**= self absorption coefficients

**_sg**= conversions between S,S~,g,G,… Those are some built in function to calculate different physical mangitudes from neutron data. Usually you can do it also your own entering step by step the operations…**1**Tof→E**2**S~(q,w)**3**g_1(w)**4**g_(1)(w)**5**G_1(w)**6**G_(1)(w)**7**c(w)**8**c(w)/T^3**9**u^2(w)**10**X''(q,w): Susceptibility calculation. It will calculate the susceptibility from the data. That is to say: Susceptibility = S(q,w)**11**q(2th,w)**12**exp(-2W)**13**1/n(w;T)**14**1/n~(w;T)

**_tx**= nonlinear transformation of x axis (S(q,w)↔tof-counts)**-1**tof → w**1**w → tof

**_mcc**= Monte-Carlo convolution
