    130130The hard-coded nominal defaults for NEUT can be found in `$NEUT_ROOT/src/reweight/NFortFns.cc`. These are also the physical units of the parameter (e.g. MaCCQE default is 1.21 GeV in NEUT).
    131131
    132 The actual physical parameter value is found by `par_value = nominal * (1 + par_var * 1-sigma)`.
     132The actual physical parameter value is found by <span class="code">`par_value = nominal * (1 + par_var * 1-sigma)`</span>.
    133133
    134134The output of the fit is in the units of `par_var`, not `par_value`. So an output for `MaCCQE` of `0.7` would equate to `1.21*(1+1*0.165) = 1.35` GeV.
