Aug 27, 2021 - Number of CIB hot pixels

We have had some discussion about how magnification leads to pixels being really hot. We looked into how big this problem really is. In the following table we show how many pixels in our CIB maps are above the Planck thresholds:

Number of hot pixels

	Unlensed	Lensed 1 + 2 kappa	Lensed 1/(1-kappa)^2
217 GHz	261	262	452
353 GHz	1609	1608	1923
545 GHz	14352	14392	14906

We see that the full magnification does not really blow up the number of super hot pixels, except for the 217 GHz map, where the total number of hot pixels is really small.
