Hi Marcin,

Good to hear from you.

L_grav has the integrated eps_grav.   but you are right, it isn't in

lg_L is the energy leaving as photons, not the energy being produced.
See below for how you can add whatever you want for total energy

all of the nuclear reactions are assigned a category;  burn_ne and  
and 2 of the categories.   to see which reactions are in those  
look at data/net_data/reactions_list.   Searching for 'burn_ne' shows
reactions such as ne20(a,g)mg24, ne20(a,p)na23,and others.

Happily, you can add columns yourself by editing run_star_extras.
Change the routine 'how_many_extra_log_columns' to return the
number of extra columns you want to add.  Then change the
routine 'data_for_extra_log_columns' to give the values.
There is a commented out example already there, so you can
use it as a start.

Good luck!
