Table 1: Parameters of Gaussian fits of the SiO(2-1), H¹³CO⁺(1-0) and HCO(1-0) lines of Fig. 6. Errors (in brackets) are 1 $\sigma$ values.
Table 2: SiO(2-1) and CH₃OH(2 $_{\rm k}$ -1 $_{\rm k}$ ) luminosities of a sample of bipolar outflows. Column 2: mass of the class 0 object; Col. 3: luminosity of the class 0 object; Col. 4: SiO luminosity integrated within the SiO emitting region of the outflow; Col. 5: SiO-to-CH₃OH total luminosity ratio; Col. 6: surface density of outflows required to obtain the mean I(SiO) in the northern spiral arm+nuclear ring of IC 342; Col. 7: references: a: Bachiller et al. (2001); b: Gueth et al. (1997); c: Fuente et al. (2005b); d: Codella & Bachiller et al. (1999).
Table 3: SiO emission in external galaxies. Column 2: SiO abundance averaged within $28\hbox {$^{\prime \prime }$ }$ (from observations with the IRAM 30 m telescope); the averaging scale is ${\sim }0.5$ kpc, for NGC 253, IC 342 and M 82, and ${\sim }2$ kpc for NGC 1068; Col. 3: components resolved with the PdBI contributing to the global SiO emission; Col. 4: SiO abundance in the resolved components; Col. 5: mechanism proposed to be enhancing the SiO abundance; underlying physical process, in brackets (DW stands for "density waves''); Col. 6: references: a: García-Burillo et al. (2000); b: this work; c: García-Burillo et al. (2001b); d: Usero et al. (2004); e: Martín-Pintado et al. (2005, in prep.).
