Sc II: the 'S' Classification defines this galaxy as a Spiral, as a pose to an Elliptical (E) or Irregular (Ir). There are two main classifications within the Spiral family: an Sa, which is characterised by tightly wound arms, and a large, prominent Nucleus, and Sc, which is defined by loose arms and a relatively inconspicuous nucleus. As well, an Sb would be between these two classifications, and would be denoted by a + or - if it was closer to one of the two. As well, galaxies are subclassified by their luminousity values: Supergiant galaxies are designated by the Roman numeral I, bright giants II, giants III, subgiants IV, and dwarfs V.(SC 2000.0, pxxix)

Color Designations of Galaxies: The method of determining a galaxies color used here is the one invented by de Valcouleurs. In essence the color index (B-V) is taken by determining the Blue level (B)-the yellow level (V) to determine the UBV color index, which ranges from approximately 0.3 to 1.0. Generally smaller values indicate a greater number of young, hot, blue stars. A spiral galaxy is usually in between these numbers. (SC 2000.0, pxxix)

Radial velocity: This is a determination of the speed of the galaxy, corrected for the solar system's motion arond the Milky way. A positive number means that the galaxy is speeding away from our Solar system. Heliocentric radial velocity (The without the correction for the motion of the solar system) is determined by subtracting 300sinlcosb, where l and b are the objects Galactic Longitude and Latitude.(SC 2000.0 p316)
