The project of the informational system creation on the problem of evolution of radio galaxies, as a part of the "Big Trio" project aimed on studing of distant radio galaxies, is designed. This system allows a user to operate with simulated curves of spectral energy distributions (SED) to estimate ages and redshifts by photometry data. Authors use SEDs of several models for different types of galaxies. ... The HTTP and e-mail access is organized to this system. ...

The parameter multiple takes the value M if the object belongs to a multiple system. For example, a galaxy belonging to a pair of galaxies have multiple=M . Presently multiple accounts for the association in projection on the sky and therefore does not reflect for sure a physical association: members of "false" pairs will have multiple=M . ... The simple membership to a cluster of galaxies does not imply a galaxy to carry multiple=M . ... HyperLeda . ...
