Notes.

^(a)

Only the absorption part, between velocity (V_LSR) 57.6−66.2 km s^-1.

^(b)

The rms values are measured with the resolutions of the original observation settings (Table 1).

^(c)

T_mb scale.

^(d)

FWHM.

^(e)

Value is derived from a Gaussian fit using the software CLASS.

^(f)

The uncertainties only include the statistical noise and not the calibration uncertainties.
