Erratum for: A&A 676, L1 (2023), https://doi.org/10.1051/0004-6361/202347174

Several errors were inadvertently introduced in two tables during the production process. In Table 1, the left arrows were changed to right arrows, and in Table A.1, spaces were inserted before the decimal points of the values. The corrected tables are presented here.

Table 1.

Ground state rotational transition frequencies of H2CCCH+, determined by laboratory and astronomical detections.

Table A.1.

Calculated and experimental spectroscopic parameters of H2CCC and H2CCCH+ (in MHz). Equilibrium rotational constants calculated at the ae-CCSD(T)/cc-pwCVQZ level of theory; zero-point vibrational corrections ΔA0, ΔB0, ΔC0; and centrifugal distortion constants calculated at the fc-CCSD(T)/ANO1 level. Best theoretical estimates for the rotational and centrifugal distortion constants X of H2CCCH+ are estimated as X H 2 C C C H + scaled = X H 2 C C C exp X H 2 C C C calc × X H 2 C C C H + calc $ X^{scaled}_{H_2CCCH^+}=\frac{X^{exp}_{H_2CCC}} {X^{calc}_{H_2CCC}}\times X^{calc}_{H_2CCCH^+} $ (i.e., using isoelectronic H2CCC as a calibrator).
