Catalog of supermassive black holes for interferometric observations

The paper presents a catalog of supermassive black holes (SMBH) shapened for the interferometric observations in millimeter and submillimeter wavelength ranges and based on the open sources. The catalog includes the name of the object, coordinates, angular distance, the mass, the angular size of the gravitational radius of SMBH, the integral flux of radiosource, related with SMBH, in the range $20\div 900$~GHz which is considered to be used in Event Horizon Telescope, future space mission Millimetron and others. The catalog is intended for use during the planning of the interferometric observations of SMBH shadows.
