Measurements for SMC objects

The following coordinates were measured from our HST data, and are therefore more accurate than those listed in the observing proposals and archive listings. Contour plots (postscript files) made from the [O III] image are not available yet. Also see our detailed notes on morphology, ionization, etc.
