Abstract (English):
A study of five peculiar galaxies (SPRC-69, 0.25cmSPRC-100, 0.25cmSPRC-260, SPRC-269, and SPRC-136) from the new catalog of polar ring galaxies (Sloan-based Polar Ring Catalog, SPRC). Panoramic (3D) spectral data were obtained with the 6-m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences with the using the Fabry–Perot interferometer. The large-scale velocity fields, velocity dispersion fields, and monochromatic images of objects in the H emission line were analyzed in detail. All galaxies showed the complex structure and kinematics of their gaseous components. The ``tilted-ring'' method was used to analyze the velocity fields. It was concluded that all the objects studied belong to are classical polar ring galaxies, with the exception of SPRC-100.
