title Leiden meeting model 4 with hacks
c This is one of the tests in Rollig et al. 2007, A&A, 467, 187 
c
c commands controlling continuum =========
c
c commands for density & abundances =========
grains ism 1.16 no qheat
c
c commands controlling geometry  =========
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 other commands for details     =========
failures 3
c  use leiden initialization file
init file="pdr_leiden_hack.ini"
c  This command defines the grain temperature to be a constant 20 Kelvin
constant grain temperature 20 
c  This sets the temperature to a constant 50 Kelvin
constant temperature 50 linear
c  hydrogen density 
hden 5.5
