Notes. (1) Designation of the velocity components. (2) Centre velocities of the HCO+ absorption. For B0355+508 from Liszt & Lucas (2000). For B0212+735 from Lucas & Liszt (1996). (3) FWHM of the HCO+ absorption. From Lucas & Liszt (1996). (4) For B0212+735 from Lucas & Liszt (1996). Some τ(HCO+) for B0355+508 from Lucas & Liszt (1996) had slightly changed in Liszt & Lucas (2000). We listed the updated values from Liszt & Lucas (2000). (5) B0355+508 data from Liszt & Pety (2012). B0212+735 data from Liszt & Lucas (1998).
