The sample of galaxies used in this section is presented in tableA1 andconsists of 245 distinct objects with simultaneous measurements ofintegrated HI line fluxes and CO(1-0) line fluxes. The latter were drawnfrom nine catalogues in the literature, and, where not given explicitly,recomputed from indicated H2 masses by factoring out thedifferent X-factors used by the authors.(1 data file).
