Notes. The molecular parameters of v30 = 1 are expressed as Xv = 1 = Xv = 0 + ΔX and for v30 = 2, they are Xv = 2 = Xv = 0 + 2ΔXv30 = 1 + ΔΔX. Numbers in parantheses represent the uncertainty compared to the last quoted digit. Δχaa in Müller et al. (2016) was fit on the ground-state value from Vormann & Dreizler (1988). Other ground-state parameters used in Müller et al. (2016) were from Belloche et al. (2009). The parameters determined in this work are based on the up-dated ground-state parameters. WRMS was calculated on the fit of all lines including v30 = 1 and 2.
