We point out that no decision on the reduction was made
and that the S reduction should be preferred. Please note
that for a small number of transitions some of the
intermediate spin quanta are different from those in (1);
this may be a consequence of subtle differences in the
assignment procedure in the respective fitting programs.
These transitions are labeled at the end of the lines
in the line file.
The data set is limited in terms of quantum number coverage.
Therefore, transitions were truncated at 115 GHz and at
F = 20. Ka was limited to 1 for
b-type transitions and to 2 for a-type transitions.
Nevertheless, the calculations should be sufficiently
accurate and extensive for searches in cold sources.
Transition frequencies with calculated uncertainties
exceeding 0.1 MHz or with Ka = 2
should be viewed with great caution.
The dipole moment is from a coupled cluster
quantum-chemical calculation from (1).
