[Pw_forum] ld1.x testing mode

[hichem bouderba]

dear all,
 in INPUT_LD1.html about ecutmin,ecutmax,decut we have :
"
Parameters (Ry) used for test with a basis set of spherical
Bessel functions j_l(qr) . The hamiltonian at fixed scf
potential is diagonalized for various values of ecut:
ecutmin, ecutmin+decut, ecutmin+2*decut ... up to ecutmax.
This yields an indication of convergence with the
corresponding plane-wave cutoff in solids, and shows
in an unambiguous way if there are "ghost" states
"

how does ld1.x say "there is a ghost state somewhere" ?

when testing a PAW with ld1.x I have the following error:

"

what does it mean ?
thanks.
