I don't have any..
I hope this info from the adomic_doc/INPUT_LD1 file might be useful:
       rho0 = charge at the origin: when the Rabe-Rappe-Kaxiras-Joannopoulos
             method with 3 Bessel functions fails, specifying rho0 > 0
             may allow to override the problem (using 4 Bessel functions)
             Typical values are in the order of 0.01-0.02       (default 
0.0)
 
best, stefano
