anisotropy frequency dependent dielectric function from GW

[yuanxun]

Deer All,
How can I frequency dependent dielectric function from GW calculation?Thanks for suggestion!

To get the dielectric, i found there are 9 colomns of chi0(G,G') (following) in the output file?Can someone give some short explanation about it's meaning? Thanks!

chi0(G,G') at the 1 th omega 0.0000 0.0000 [eV]
1 2 3 4 5 6 7 8 9
1 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000
0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000

2 0.000 -8.006 0.192 0.777 0.398 0.771 0.401 0.788 0.406
0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000 0.000

Dear all,
I found parameter in input list:
gw_nqlwl
Mnemonics: GW, Number of Q-points for the Long Wave-Length Limit
This may be helpful.
