<pre style="line-height: normal;">Dear Mr/Mrs
I have a question about the dimensions of the velocity in this progam.
I am using the postw90 module to obtain the interpolated energy eigenvalues and the velocity at arbitrary k point.</pre><pre style="line-height: normal;">It can be seen from the output file that the <span style="font-family: Verdana;">energy eigenvalues is in the unit of eV, but how about the unit of velocity? </span></pre>
