Defined dimensionless in a weighted least-squares fit2 : Ray’s asymmetry parameter defined by = (2B – A – C)/(A – C) Pseudo-inertial defect: defined by = Ic – Ia – Ib Uncertainties: The uncertainties represent one standard deviation Significant digits: the number of significant digits of each fitted constant is listed on the diagonal of the correlation matrix Units: the observed frequencies, the residuals, the distortion corrections, and the rotational constants are in MHz, the quartic centrifugal distortion constants are in kHz, the sextic centrifugal distortion constants (if applied) are in Hz, and the principal axis inertial constants and the inertial defect are in u Å2 10 Table 4S.
