Modulation results at high ℓ. The shaded bands show the 68% spread of p-values for asymmetry taken from Commander simulations with a mean p-value less than 10% for ℓ >  1000. The dark green band (dark green boundaries) represents results computed from the OE data set using the full-mission common mask, the grey band (with grey boundaries) to the same data set analysed with the OE common mask applied, and the light green band (with light green boundaries) corresponds to the HM data set analysed using the HM common mask. The red solid lines show the same three cases for the data: lower line, full-mission common mask; middle line, OE common mask; and upper line, HM common mask.
