   Fig. 2(o) - Identification charts for H II regions. The CCD frames used here
 included H{alpha} plus the continuum so that their relationships to field
 stars are apparent. They were studied and measured on frames from which the
 continuum had been subtracted. All are shown to approximately the same
 limiting surface brightness except Figure 2(g). which is a lighter print to
 show details of the high-surface-brightness objects.
