ThermalNeutronDtoTOFFunction

Description

ThermalNeutronDtoTOFFunction is a function to calculate TOF from d-spacing values for ThermalNeutronBk2BkExpConvPVoigt. It is defined as

TOF = n(zero + dtt1 \cdot dh)+(1-n)(zero_t + dtt1t\cdot dh - \frac{dtt2t}{dh})

where

n = \frac{1}{2} \mathit{erfc}(\text{Width}(t_\text{cross} - d^{-1})).
