The O2-N2 continuum is producing spuriously strong absorption at the red-end of its range. This is approximately from 5.3 um to 7.8 um (bands 132-152 in Honeyside256).
I have tested various gas combinations, and it seems that only this pair is impacted. I don't know why. It is derived from HITRAN, which is trustworthy, so maybe there's some issue in the spectral file generation.
As a workaround, I have disabled O2 opacities in AGNI through the variable atmosphere.BLACKLIST_RT. It is treated properly in most of the code, but the O2 mass mixing ratio passed to radiance_calc is always set to zero.
