6. Although the units of the Hubble constant are a hit mixed, they are suitable for the subject. Redshifts can be expressed as velocities in kilometers per second and distances in parsecs (1 parsec = 3 262 light-years = 3 086 x 10th meters) or mega parsecs (millions of parsecs). A parsec is a good unit, because the distances to nearby stars are a few parsecs and mega parsecs are good units because the distances to nearby galaxies are a few rnega parsecs A .similar unit that is not standard, but useful in a particular context is the Smoot, used at MIT. A Smoot is the length of Oliver R Smoot 1962 5 feet 7 inches The length of the Harvard Bridge, across which MIT undergraduates must walk on freezing Massachusetts nights is 364 4 Smoot.s plus one ear

This survey pioneered the large-scale use of electronic cameras scanning across patches of the sky to select the galaxies and the use of fiber optics to obtain the spectra of many galaxies simultaneously.
