Power Spectra of 13CO and Bolocam

Examples of power-spectra in the left panel:

The BGPS power law is fitted only over the "valid" range, which is shown in black. The BGPS power spectrum agrees pretty well with the Herschel power spectrum. Both are substantially steeper than (any) of the 13CO power spectra. Unfortunately, this somewhat calls into question any comparison between the data sets - it seems most likely that 13CO and dust actually trace different mass, particularly since both Herschel and Bolocam show a "bump" centered at 6' (10^-1 image sizes) that is not evident in 13CO.
