Main properties of the CO clouds identified in this work. Here are shown the velocity dispersion-size (radius) relation (top panel) and the virial masses vs. CO(1-0) line integrated luminosities (bottom panel). The limited angular resolution of the CO data analyzed here allow us to include only an upper limit for r_CO (black triangles-arrows) (see Sect. 2 for more details). The figure also includes results of CO structures detected in other dwarf galaxies: M33 (Bolatto et al. 2008); LMC (Wong et al. 2011); and a compilation from the literature as included in Rubio et al. (2015) corresponding to WLM, SMC, and M31.
