See chamber description

Data collection description:
Spectra were collected with the Ocean Optics (OO) spectrometer at a sampling rate of 1Hz in a fixed location mounted in the corner of the chamber enclosure pointing toward the middle of the reaction chamber bag.

Data analysis description:
The wavelength-dependent response of the Ocean Optics spectrometer was calibrated using…. [ender brief details here]. The light flux spectrum calibrated for a wavelength-dependent response was normalized to compute an absolute flux spectrum using a J_NO2 actinometry measurement to yield an average/integrated light flux for the entirety of the chamber reaction volume.
