hi

is there any special trick for computing RESPONSE with BAND
on hexagonal cells?

it seems to be rather tough to converge the response to anything physical
(values of Im(epsilon) and Re(epsilon) of exponents of 200-300...)
with the better tetrahedron k-point integration. On the other hand, the
linear method (even number of k-points) leads to really unaffordable
large numbers of points, still giving not too physical values of epsilon

i would appreciate any hint / recipe on this matter

thanks

Manolo
