Table 2

Probabilities of finding higher or lower σ values in at least one quadrant of the simulated MC maps than in the Planck SMICA2 map.

Map	σ_SEQ	P1^a	σ _SWQ	P2^b	σ _NEQ	P3^c	σ _NWQ	P4^d

SMICA2 + mask-rulerminimal	1891.99	27.1%	506.74	25.3%	308.32	0.6%	420.39	8.8%
SMICA2 + U73	1356.25	43.8%	567.98	55.1%	302.18	1%	810.99	88.6%
SMICA2 + UT78	2373.69	10.9%	985.71	94.6%	677.26	64.1%	558.94	41.1%
SMICA2 + U66	1257.18	64.1%	829.16	85.9%	374.49	5.4%	1233.65	65.6%

Notes. We show the effect in each quadrant of different masks provided by the Planck team.

^(a)

Probability of finding σ_MC >σ_SEQ;

^(b)

probability of finding σ_MC <σ_SWQ;

^(c)

probability of finding σ_MC <σ_NEQ;

^(d)

probability of finding σ_MC <σ_NWQ. An exception was made for SMICA2 + U66 where the probability of finding σ_MC>σ_NWQ was calculated instead.
