Sep 02, 2021 - Cut on galaxy level

At some point we were discussing possibility of doing the cuts at the level of individual galaxies - if its lensed flux is above the threshold, throw it away - rather than at the map level. We see that it helps and leads to better results than doing no cuts at all, but still not enough:

To see where this is coming from, we compared pixel flux distributions for the three possibilities (no cut, map cut and galaxy cut) and found that while the galaxy cut helps, there are still plenty of pixels above the Planck cutoff. The vertical line is the cutoff; the accumulation on the left side is zero flux pixels padded by 100.
