    R_MT_Pd = 2.1 bohr<br>
    R_MT_O = 1.1 bohr<br>

    To me, it looks like the l_max^wf is the <font color="#ff0000">lmax</font>
    value given in the WIEN2k 17.1 usersguide on page 125 in section
    "7.5.3 Input" [

    ].  The l_max^pot is the <font color="#000099">lnsmax</font> value.<br>
    <br>
    The E_wf^max might be from the equations used in the article titled
    "Electric field gradients at 111In/111Cd probe atoms on A-sites in
    211-MAX phases" [ <a

    Kmax = rkmax/RMT_min<br>
    <br>
    E_wf^max = Kmax^2<br>
    <br>
    or<br>
    <br>
    rkmax = RMT_min * sqrt(E_wf^max)<br>
    <br>
    Since RMT_min = R_MT_O:<br>
    <br>
    rkmax = 1.1 * sqrt( 20 ) = 4.919<br>
    <br>
    So E_wf^max seems to correspond to the <font color="#009900">rkmax</font>

    value in case.in2 of the WIEN2k 17.1 usersguide on page 134 in

    <br>
    In other words:<br>
    <br>

    GMAX = sqrt(E_pot^max) = sqrt(196) = 14<br>

    However, I don't know for sure as it may be that authors are not
    using a common definition, so if you are getting those values from
    an article, you would have to ask the author (or corresponding
    author) of that paper to find out for sure what they used for their
    definition and how they got their values.<br>
    <br>
    Instead of E_wf^max for example, other might be using Ecut =
