Morphological type: type

The morphological type, or Hubble type, is coded from early to late types as: E -- E-S0 -- S0 -- S0-a -- Sa -- Sab -- Sb -- Sbc -- Sc -- Scd -- Sd -- Sm -- Irr
For barred spiral galaxies the types are: SBa -- SBab -- SBb -- SBbc -- SBc -- SBcd -- SBd -- SBm
There are also the types: S? and E? for uncertain classification.

The morphological type is also coded as the de Vaucouleurs numerical type: t, and other information about the morphology are contained in the bar and ring parameters and to some extend in thecompactness and multiple parameters.
