Betreff: PDR cosmic-rays 


Dear All,

A brief and simple correction to the announcement
we just circulated re the various benchmarking runs.

For the cosmic-ray ionization processes we ask you
to limit to the following processes and rates


H2 + CRP --> H+ + H      at a rate 0.02*ZETA
H2 + CRP --> H + H       at a rate 0.1*ZETA
H2 + CRP --> H2+ + e     at a rate 0.88*ZETA

H + CRP --> H+ + e       at a rate 0.46*ZETA

He + CRP --> He+ + e     at a rate 0.5*ZETA

where again ZETA = 5e-17 s^-1

Also, please run models to an AV of at least 10.

Thanks,

Markus and Amiel
