Energy-dependent transport correction factor

The energy-dependent transport correction factor is read using the set trc option. The data file contains energy-dependent correction factors:

$f(E) = \frac{\Sigma_\mathrm{tr}(E)}{\Sigma_\mathrm{tot}(E)}$

at one or multiple temperatures. Histogram interpolation is used between energy points and linear interpolation between temperatures. The file formats is:

NE E1 E1 ... ENE+1
NT T1 T1 ... TNT
F1,1   F2,1  ...  FNE,1
F1,2   F2,2  ...  FNE,2
...
F1,NT  F2,NT ...  FNE,NT

where:

NE	: is the number of energy groups
E1 ... ENE+1	: are the group boundaries in MeV (in ascending order)
NT	: is the number of temperatures
T1 ... TNT	: are the temperatures in kelvin (in ascending order)
F1,1 ... FNE,NT	: are the correction factors corresponding to each energy group and temperature

Notes:

• If the number of temperatures is set to zero, no values are read and the same distribution is applied at every temperature.
