Specific Corrections and Reanalysis of the Data:

The substance of the present HCN tables was taken from the excellent review by A. Maki [74001]. This has been supplemented with new data from several recent publications. It should be noted that the calculated hypothetical transition frequency for the J = 2-1 of H13C14N given in table 16 of [74001] is erroneous. The correct measured frequency is given in the microwave spectrum of HCN. The asterisks shown in the uncertainty columns of the spectral line table for HCN indicate that the transition frequency is a calculated rather than a measured value.
