As in that study, additional data were taken

The ground state of HO13CO+ is perturbed
by the excited v5 = 1 state.
Since the molecule has been detected thus far in cold
environments only, transition frequencies with
Ka = 3 and higher were omitted from the fit,
and the predictions were limited to Ka ≤ 2.
Predictions with uncertainties larger than 0.2 MHz
or b-type transitions with Ka = 2
should be viewed with caution.
The dipole moment was assumed to agree with that of
HOCO+, see e045522.cat.
Note that the values
of the two components have essentially been interchanged
with respect to earlier calculations.
