<div>Dear all,</div>
<div> </div>
<div>In wien2k /SRC_lapw1 the file lopw.f generates the LAPW (K+G)-vector for local orbitals, </div>
<div>Could anyone give me some detailed reference for fictitious planewave construction for local orbits?</div>
<div>Actually local orbits do not need to couple any planewave outside the MT sphere.</div>
<div> </div>
<div>Thanks very much.</div>
<div> </div>
<div>Best, </div>
<div>Wenmei Ming </div>
