For the LLGHGs, the radiative forcing formulas give radiative forcing as SARF. Make parameters to allow for adjustments from SARF to ERF. Possible to add another column in the gases file (header ADJUSTMENT)?
Or send as parameter.

+5% for CO2 -14% for CH4 +7% for N2O +13% for CFC-11 +12% for CFC-12
For methane this feedback factor is already taken into account:
q_ch4 = 1.0 / 1.14 * q_ch4 # + FORC_PERT(yr_ix,trc_ix))
This is the reason why the calculated RF in the SCM does not match the ERF timeseries from AR6 for halocarbons and N2O.
