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.
