Accurate Positions for MCG Galaxies
We have measured accurate celestial coordinates for 4741 extragalacticobjects, primarily drawn from a list of MCG galaxies with no recentlypublished accurate positions. The standard deviations in the newpositions depend slightly on the measurement method but are on the orderof 1.0" to 1.2". Standard deviations in the original MCG positions areconfirmed to be at the 1.5′-2.0′ level. These new positionswere integrated into NED in 1997 December.

Self-regulating star formation in isolated galaxies - Thermal instabilities in the interstellar medium
Using the Parravano (1987) hypothesis, the influence of dust content, UVradiation, primary cosmic ray ionization rate, and metal abundance uponthe conditions for cool cloud condensation are investigated. Thehypothesis is tested for several isolated and interacting galaxies. Itis suggested that the UV radiation regulates star formation and that thedust content plays an important role in determining the star formationrate.
