Galactic Foreground Constraints from the Python V Cosmic Microwave Background Anisotropy Data
We constrain Galactic foreground contamination of the Python V cosmic microwave background anisotropy data by cross correlating it with foreground contaminant emission templates. To model foreground emission we use 100 and 12 µm dust emission templates and two point source templates based on the PMN...
