Abstract
We study Galactic emission foreground contamination of the Owens Valley Radio Observatory and UCSB South Pole 1994 cosmic microwave background anisotropy data by cross-correlating with templates of infrared dust emission and new high-resolution Virginia Tech Spectral Line Survey (VTSS) and Southern Halpha Sky Survey Atlas (SHASSA) Halpha data. Halpha data provide rough upper limits on the level of free-free emission in the data sets. The cross-correlation analysis does not contradict a two-component foreground emission hypothesis, with the two dust-correlated components being free-free emission and spinning-dust emission.
