Notes. Number of void galaxies in the Voids174 sample with morphological classification using different catalogues: DS18 catalogue, Galaxy Zoo 1 (GZ1), Galaxy Zoo 2 (GZ2), and using the concentration index (CI) computed from photometric SDSS data. The columns correspond to: (1) catalogue or method used to classify galaxy morphology; (2) number of void galaxies with morphological classification and the corresponding percentage of the total number of void galaxies in the Voids174 sample (26 864 galaxies); (3) number of galaxies classified as early-type in the corresponding catalogue and percentage of galaxies with respect to column (2), i.e. fraction of early-type galaxies (f_Early−type); (4) same as (3) but for late-type galaxies, with the corresponding fraction of late-type galaxies (f_Late−type). Uncertainties are given considering a binomial distribution as $e_f=\sqrt{\frac{f(1-f)}{N_T}}$, where f is the relative fraction for the total number of N_T galaxies classified in each sample shown in column (2); and (5) fraction of galaxies with early/late-type morphology in common with the DS18 morphology classification, respectively. In this case, uncertainties are estimated considering N_T as the total number of galaxies with early/late-type morphology in each catalogue shown in columns (3) and (4), respectively.
