| - | * Amy: descope, we could get 3-color, and therefore the solution is 2-color pixel, tech chapter or risk, not systematics; | + | * Amy: we need to talk about if we don’t have three colors; how we distribute, majority goes to systematics; |
| - | * Shaul: agree with; point out it will not be that we won’t have, it will be like we have those detectors, but systematics exceeds; if you have sensitivity, | + | * Amy: descope, we could not get 3-color, and therefore the solution is 2-color pixel, tech chapter or risk, not systematics; |

| + | * Shaul: from science point of view, the impact is on noise, more 1/f, not easy to quantify; that is something has to be assessed by simulation | ||
| + | * Shaul: all of the small scale science should be fine, the only science affected could be largest angular scale and B modes; we can simply say "the effect on the largest angular scale will be accessed" | ||
