All Tables

Table 1: Source of the velocity dispersion profiles or 2D maps that we used to construct the samples.
Table 2: Results of the morphological classification of dust structure and H $\alpha$ nuclear and circumnuclear structure of the 20 galaxies from the $\sigma$ -drop sample. ID of the galaxy (Col. 1); morphological type (RC3, Col. 2); nuclear activity (from NED, Col. 3); distance in Mpc, (Col. 4); B magnitude (NED, Col. 5); axis ratio d/D (NED, except in NGC 1097 where we measured d/D from the H $\alpha$ ring and NGC 6814 that looks face-on), (Col. 6); dust structure within the radius r_c (Col. 7); nuclear H $\alpha$ structure (Col. 8); circumnuclear H $\alpha$ structure (Col. 9). Statements such as ``Ring+Patchy'' describe in which order we find each H $\alpha$ structure, starting at the nucleus.
Table 3: As Table 2, now for the 20 control sample galaxies.
Table 4: Statistical properties of the $\sigma$ -drop and control samples, showing mean and median values of the four parameters used for matching the samples.
Table 5: Sizes of the $\sigma$ -drop and $r_{\rm {c}}$ .
Table 6: Bars in the sample galaxies. The data come from the RC3 except in the cases that are explained in the text.
Table 7: Luminosity profiles of the studied galaxies.
Table 8: Emission in CO and H I by the sample galaxies. Both the fluxes and the errors are in units of 10⁵⁴ W km (Hz s)^-1 for CO, and of 10⁵² W km (Hz s)^-1 for H I. The error column corresponds to the photometric error and does not take into account the uncertainty in the distance. In some cases, no error estimate is given for the H I emission because this was not given in the literature. A hyphen (-) means that no data are available.
Table 9: Statistics of CO emission in the $\sigma$ -drop and control samples. All data are in units of 10⁵⁴ W km (Hz s)^-1.
Table 10: Statistics of H I emission in $\sigma$ -drop and control samples. All data are in units of 10⁵² W km (Hz s)^-1.
