Notes. ^aFollowing Lindsay & McCall (2001). ^bDetermined from the lowest accessible level of $H_{3}^{+}$ ${\rm{H}}_3^ +$ , J, K = (1, 1). ^cComputed using an aperture of 0.1″ (a solid angle of 2.35×10⁻¹³ sr), the same aperture used to extract the observational data. ^dFrom Schroetter et al. (2025b).
