hessian job

Dear FireFly users

I have performed IRC-calculation(MCSCF) for some system and then, mrmp2 energies for these irc points. So a new geometry of saddle point has been obtained. I need hessian to compute, and then thermodynamic functions. In what method should i calculate hessian and for what geometry (mcscf or mrmp2 and other). As far as i now mrmp2 hessian is yet unavaliable for mrmp2.
