Maps of increments for the component separation applied to Herschel Spider observations. The Neperian logarithm of the absolute value of the increments computed at θ = 0.4, 0.8, and 1.6 arcmin lags are compared for the input (d_S, top row) and output (, bottom row) maps. We substracted the log of the standard deviation of each map. Zooming in on these maps allows for a review of the smallest scales.
