Dear Marty,
There is a small problem remaining.
When i do as you said,
*[yangxu@WimaxServer 20110113-10]$ /opt/siesta-3.0-rc2/bin/optical *
* Do you want to include a Drude term?*
* This is typically needed for metals*
* if yes: enter 1, if no: enter 0*
*1*
* We need an empirical relaxation time*
* Enter the invers in Ha units*
*
*
here,what is the meaning of "Ha units"?Does 'Ha units' means HATREE,ie
atomic units,or something else?

BEST WISHES!
