[SIESTA-L] lattice constant

[mashiat alaaii]

Dear All,
Hi.
I guess that siesta needs LatticeConstant for making bands file.
If positive, which lattice constant should be chosen for a hexagonal
structure?
I am trying to compare siesta results to abinit and quantum espresso for a
very simple 8-atom SiC at first.
the lattice parameters are: 3.069228 3.069228 10.04865 Ang 90 90 120 for the
block of latticeparameters, but I don't know what latticeconstant should be.
Thank you.
