[QE-users] Is there "recommended" values of cutoffs for ONCV pseudopotentials?

[mkondrin]

Dear QE developers and users,

I wonder is there recommended values of energy and charge density 
cutoffs for norm-conserving pseudopotentials like ONCV ones? For PAW 
pseudopotentials which are available at the official QE site these 
values are written in the corresponding files but for ONCV 
pseudopotentials this information is absent. Or should it be found 
experimentally by try and error starting from the rule of thumb value 
(70 Ry) ?

Thanks in advance.

Sincerely yours,
M. V. Kondrin
