摘要:Table 1 of the paper “Discovery of HC 3 O + : The chemistry of O-bearing species in TMC-1” contains two typographical errors. ThecorrectvaluesaregiveninTable1ofthiscorrigendum.Also, the units of the derived distortion constant have to be corrected. The value derived from the astronomical observations is D = 0.5106±0.0047kHz, and the one obtained from the merged fit to thelaboratoryandastronomicaldatais D = 0.5064±0.0030kHz.
