5. Sage et al (1992) note that the star formation rate for star forming dwarf Irregulars is generally higher than in starforming ellipticals, but not the starforming efficiency(SFE). This makes II Zw 40 an unusual case. The SFE is defined as the ratio between the mass which is converted into newly formed stars and the entire mass of the starforming region.
