Table 3: Results of the search for truncation radii and comparison to the results for the "hunting for warps'' of García-Ruiz et al. (2002). The galaxy types have been taken from that paper. The asterix in the third column indicates the galaxies for which the DSS2 had to be used. $R_{\rm H{\small I}}$ is the radius at which the face-on H I surface brightness is 1 $M_{\odot }$ pc-2 and has been taken from García-Ruiz et al.
