1 Overall distribution of gas and light in the Galaxy
Review of current research on Galactic Center (E. Bloom) Issues in modeling the diffuse emission of the GC Strategies for obtaining column densities Subtraction of point sources as the way to define diffuse emission model – problematic H I optical depth effects – no magic bullet Dark molecular gas – IAG & JMC can provide column densities for |b| > 5° (after some further investigation) but no good method for extrapolating to the plane Galactic distribution of gas and CR sources – axisymmetric vs. real life
