* Encrease Tmax for computation of light curves for small rout
  due to inner echo and GR effects close to black hole.

* For the lag-frequency dependence, if the Eref1 (par31) parameter is negative,
  the energy reference band is abs(par31) to abs(par32) excluding overlaping
  part with the energy band of interest abs(par29) to abs(par30).
