Power spectra comparison of TYPE 1 and TYPE 2 CO J =1 → 0 maps (top) and J = 2 → 1 maps (bottom), with and without an attenuation mask to reduce the amplitude of emission in the brightest 2% of pixels (shown in the top panel of Fig. 3). The TYPE 1 J =1 → 0 have lower power compared to the TYPE 2 map. For the CO J = 2 → 1 line emission, the TYPE 1 map has higher power compared to the TYPE 2 map. Both of them have higher power than the Commander CO J = 2 → 1 map. The discrepancy between TYPE 1 and TYPE 2 CO J = 2 → 1 power spectra largely goes away when masking the regions of strongest CO.
