line 153-155 in nn.f is (19.1)
      iix=5
      iiy=5
      iiz=5

Change these to something larger (e.g. 10), or use similar to the lines
below

        iix=max(1,nint(dstmax/a(1)))+1
        iiy=max(1,nint(dstmax/a(2)))+1
        iiz=max(1,nint(dstmax/a(3)))+1
        iix=min(nint(dfac+1),nint(dstmax/a(1)))+1
        iiy=min(nint(dfac+1),nint(dstmax/a(2)))+1
        iiz=min(nint(dfac+1),nint(dstmax/a(3)))+1
