Notes. Results of the Gaussian fits. For each object observed with the IRAM 30 m, the first line displays the CO(1-0) and the second line the CO(2-1) results.

(a)

FWHM.

(b)

Peak brightness temperature.

(c)

Obtained with the standard MW conversion ratio. In the two cases where only one transition was detected, the table shows the rms Tmb for 50 km s−1 channels and 3σ upper limits on other parameters, assuming Δ V of 300 km s−1.

(d)

Detected values for the NGC 128 offset pointing in the H I bridge.
