Leveraging improvements to the $\\textit{HST}$-COS wavelength solution, we co-add isolated lines within four fluorescent progressions ([$\\textit{v'}$,$\\textit{J'}$] = [1,4], [1,7], [0,2], and [3,16]) to improve signal-to-noise, and we fit each co-added line profile with one or two Gaussian components.
