title Leiden meeting model 6 with hacks
c This is one of the tests in Rollig et al. 2007, A&A, 467, 187 
c
c commands controlling continuum =========
c Use the Draine 1978 field, for a semi-infinite slab we have to use half
c the requested value, so the actual value
c they want for the model is actually twice the value below
table draine 50000
extinguish 24
c
c commands for density & abundances =========
c  Define the abundance of PAHs so we can reproduce the same photoelectric
c heating curve as BT94 
c  We have also scaled the grain abundance to achieve the desired AV/NH ratio 
* grains PAH no qheat 40
grains ism 1.16 no qheat
c  hydrogen density 
hden 3.
c
c commands controlling geometry  =========
c
c other commands for details     =========
c  use leiden initialization file
init file="pdr_leiden_hack.ini"
c
c commands controlling output    =========
save performance "pdr_leiden_hack_v2.per"
