Dear  list:
   I did a test calculation on bands convergence of GW calculation with 
abinit 5.6.3. But it seems that  the "nband" tag  didnot control over the number of bands in self-energy calculation, and the value for "mband" was ok which agreed with my setting for nband.
Below is my setting for GW parts and related output , any comment or advice  is appreciated.

GW  settings:
 ndtset 5
 # GW corrections
  optdriver  4  # driver options for self energy 
  getkss 2   # KSS file used
  getscr 1   # SCR file used
  nband: 200  # bands for self energy
  nband+ 50
  ecutwfn  24 Ha # 
  ecutsigx  24.0 Ha
  nkptgw    1    # 
  kptgw
     0.000 0.500  0.500
  bdgw  54  55
