pair_style gayberne for 2d LJ fluid for ellipsoid molecules

Hi,

   I am simulating 2d fluid for ellipsoid molecules using Gayberne pair
potential for the interaction. I am getting following instructions from
the manual to use it:

pair_style gayberne gamma upsilon mu cutoff

· gamma = shift for potential minimum (typically 1)
· upsilon = exponent for eta orientation-dependent energy function
· mu = exponent for chi orientation-dependent energy function
· cutoff = global cutoff for interactions (distance units).

But, i am not getting idea to select upsilon and mu from the manual.
Please help me.

have you read the documentation _completely_?
including the extra information?
