Five primary molecular species are included, based on our comet photometric program and the narrowband filters we employ :

• OH — 0-0 band at 3090 Å
• NH — Δv=0 band sequence at 3360 Å
• CN — Δv=0 band sequence at 3870 Å
• C₃ — band complex center at 4060 Å but with wings extending from 3300 Å to 4400 Å
• C₂ — Δv=0 band sequence at 5140 Å

In the case of the C₃ and C₂ bands, our narrowband comet filters only "see" part of the band; our quoted fluxes have already been adjusted to the full bands, knowing the band slopes and what fraction of the total bands are transmitted by the filters. For spectra, equivalent adjustments should be made for the fluxes extracted using spectral "windows" which do not include the entire emission feature.
