VizieR Online Data Catalog: Galaxies at 0.02<z<0.1 morphological catalog (Vavilova+, 2022)
Abstract
Catalogue of the image-based morphological classification of 315776 galaxies with the absolute stellar magnitudes in the range of -24...-13 at z<0.1 from the SDSS DR9 is obtained by the CNN classifier. To create the Catalogue, we divided it into two subsamples, SDSS DR9 galaxy dataset and Galaxy Zoo 2 (GZ2) dataset, considering them as the inference and training datasets, respectively. When training the CNN classifier for a more accurate result, we took into consideration only those galaxies for which GZ2's volunteers gave the most votes. The criteria for each image of the galaxy are defined in the GZ2 project, their description is available through web-site https://data.galaxyzoo.org/.
This Catalogue contains the data on five morphological classes, where the CNN probability of galaxy to be assigned to one of the classes is as follows: cigar-shaped (75%), completely round (83%), round in-between (93%), edge-on (93%), spiral (96%). This Catalogue is supplemented with the VizieR Online Data Catalog: SDSS galaxies morphological classification (Vavilova et al., 2021A&A...648A.122V, Cat. J/A+A/648/A122) Catalogue is available in CSV format at ftp://ftp.mao.kiev.ua/pub/astro /cats/galaxies/galSDSSDR9zto0.1morph5_classes.csv. (1 data file).- Publication:
