[Pw_forum] Masses in .dyn file

[Marino Vetuschi Zuccolini]

Hello to all,
browsing the .dyn file about MgO, the header of the file is reported 
below the message. The numbers that in the code are written by ph.x 
(and read by others tools) after atomic symbols as atomic masses, 
evidently they are not, and change as the masses in &inputph section 
statement change. Are they related to reduced masses?

I try to understand the meaning from the source but the result was not 
so good...

Thanks in advance

m.
