Time-critical
-------------
No.

Objective
---------
Generate a spectroscopic sub-sample of at least 120,000 galaxies with 99% purity. The galaxies must be selected with the same selection criteria as in the wide survey. Estimates of the number density of galaxies imply a survey area of at least 40 square degrees.
