[Laurent Mercadier]

"Delay" is in my opinion too general. How about "PP800_Delay_ps"?

I am also concerned about using the delay calculated by this MDL. It is error prone because T0 is set manually and arbitrarily, sign can be inverted...

[Martin Teichmann]

I actually agree, and it is actually not such an important parameter, as the delay is also available as hRIXS_delay, which is much more useful. So I take this one out.
