Morphological type (numerical): t

The numerical code for the revised (de Vaucouleurs) morphological type is defined in RC2. The correspondance with the Hubble type is:

The morphological type is also coded as the Hubble type: type, and other information about the morphology are contained in the bar and ring parameters and to some extend in the compactness and multiple parameters.

This parameter is derived from the compilation of morphological description. The individual estimates collected from the litterature are compared and combined to give the best possible value. An uncertainty is determined.
