In addition to the regular nahoon, you will need 
-pol_data
 to run a program.

You will have to use
-nahoon_ht.f
-cond_initial_ht.dat
-osu_09_2010_ht
 for the main program, initial condition file, and the reaction network.

For type 20, the method of calculation is described in Harada, Herbst, and Wakelam (2010) in Section 2.2. 
The first column is the branching ratio, the third column is the reduced mass. 
When the reaction is endothermic, the barrier is approximated by multiplying by exp(-gamma/T), and the gamma is located on the second column. 
The polarizability and the dipole moment are in a file 'pol_data'.

Reaction types 41 and 42 are essentially the same type of reactions, but typee 41 is turned on for T<300K, and type 42 is turned on for T>=300K.
