Notes. Numbers in parentheses refer to 1σ uncertainties expressed in units of the last quoted digit. (a)Rest frequency corresponding to the hypothetically unsplit fine-structure transition. (b) Half-power beam width of the observations. (c)A conservativeuncertainty of 0.25 MHz produced by the HIPE pipeline is summed in quadrature. (d) Derived through Eq. (1).
