Maps of calibration obtained by fitting Planck TYPE 1 (top row, from J = 1 → 0 to J = 3 → 2, left to right) and TYPE 2 (bottom row, from J =1 → 0 to J = 2 → 1, left to right) maps against Dame J = 1 → 0 map in N_side = 16 super pixels. We perform a fit in any super pixel if there are 50 or more original pixels at N_side = 512 with a high signal-to-noise ratio in the Dame map. For all super-pixels where this condition is not met, we assume the mean calibration given in Table 1. These maps illustrate the variation over the sky of the ratio between the CO detected in Planck TYPE 1 and TYPE 2 maps and the CO detected in the Dame J = 1 → 0 map.
