Best fitted model to combined Band 5 and 6 NH₂CHO data for B1-c in red and data in black. Each graph shows one line of NH₂CHO with its upper state energy level and the A_ij coefficient at the top right in red and blue, respectively. The dashed green line indicates the 3σ level. The lines above the 3σ level that were used in the fitting are indicated by a green X. The lines with upper energy levels above 1000 K and/or A_ij below 10⁻⁵ are not plotted.
