Table 8-1. Track-Averaged Mesh Tally (type 1) Keyword Descriptions (Continued)
Keyword

Description
Can have from one to four numerical entries following it.
• The value of the first entry is in reference to an energy dependent response
function given on a MSHMFn card (no default).
• The second entry is 1 (default =1) for linear interpolation, and 2 for logarithmic interpolation.
• If the third entry is zero (default=0), the response is a function of energy
deposited, otherwise the response is a function of the current particle
energy.
• The fourth entry is a constant multiplier and is the only floating point entry
allowed (default=1.0).
If any of the last three entries are used, the entries preceding it must be present
so that the order of the entries is preserved. Only one mfact keyword may be
used per tally.

Must be followed by a single reference to a TR card that can be used to translate and/or rotate the entire mesh. Only one TR card is permitted with a mesh
card.
