 +====Class project 1, Problem 2====
 +I think I've found where to turn off the CNO cycle: line 246 of src/star_controls.f.
 +
 +===== Does anyone know how to turn off the CN, ON, or pp-chain cycles? =====
 +
 +--Mark Zastrow
 +
 +In ez_nuclear_data.f you can find how the different reactions are named. You can then edit them in ez_nuclear.f
 +
 +So for example to turn off the He3 + He3 reaction, change R33 = RHB*RRT(2)/2D0 into R33 = 0 !RHB*RRT(2)/2D0
