[Pw_forum] Default values used in Quantum espresso manuals

[Shaptrishi Sharma]

Hi There,
I am a new user in quantum espresso , thus I would like to ask one question
how do the default values in the quantum espresso manuals have been choosed?
I mean to say that in quantum espresso manuals we find
forc_conv_thr =1.0D-3
conv_thr =1.0D-6
etot_conv_thr=1.0D-4

How did the values calculated?

Thanks
Shaptarishi
