The entry is based on a recent report by

D. Prudenzano, C. Endres, O. Sipilä, and P. Caselli,
2017, Astron. Astrophys. 602, Art. No. A34.
As in that study, additional data were taken
from

1988, J. Mol. Struct. 190, 465.
The ground state of DOCO+ is perturbed by the
excited v5 = 1 state, albeit
to a lesser extend the HOCO+. Since the
molecule has been detected thus far in cold environments
only, transition frequencies with Ka = 4
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.
