If no numbers are given for the value of a measured splitting and its residual, the hyperfine component overlaps with the previous component. The values of the splitting and the residual refer to the respective intensity weighted averages.
^a Numbers in parentheses are one standard deviation in units of the least significant figures.
^b Residuals for DCO⁺ refer to fit with C_I kept fixed. The residuals are zero if C_I is released as two pieces of information are then used to derive two parameters.
