Will be very interesting check the spatial correlation between the WMAP data and the Planck Reference Sky.
I make some scatter plots: WMAP versus Planck Reference Sky in the pixel space for all sky maps. You can see these plots on the first column.
After that I focused into the galactic plane. I make the scatter plot using just the galactic cut [+-5 deg] and I calculated the correlation of this two set of data. I found also a renormalization between the two sets of data, calculating a linear fit and imposing that the angular coefficient equal to 1.
In the following table I report the correlation coefficient and the parameter of the fit.
In the second column I plotted the WMAP data versus Planck Reference Sky maps renormalized [both into the galactic plan].
