hex.PhC k-points

Dear mpb users

I examine the tri-rods.ctl example in mpb wiki page.
This real space structure is triangular and corresponded reciprocal
structure is hexagonal, isn’t it?
When I change the real space basis for hexagonal structure as the
following code, what will the k-points become?
Does the k-point remain still same?
best...
