Spiral and Ring Classification Catalog
(Shimakawa et al.)

Morphological classification catalog of spiral and ring features of 687,859 magnitude-limited galaxies at z=0.01-0.3 from Shimakawa et al. based on the Hyper Suprime-Cam Subaru Strategic Program Public Data Release 3 (HSC-SSP PDR3). The morphological classifications have been performed using deep convolutional neural network trained by the GALAXY CRUISE Data Release 1 (Tanaka et al. 2023). The catalog contains 385,449 spiral galaxies and 33,993 ring galaxies, respectively. More details can be found in the paper. HSC-SSP PDR3 is described in depth in Aihara et al. 2022 and also at the data release site.
The catalog is available here (48.5 MB). The meaning of each column is as follows. Please cite Shimakawa et al. if you use the catalog in your publication.
