Well, we don't know that the data get cleaner at that point. How do you know that is pure signal? That's why I asked about the frequency of the noise during that interval in another post, which seems to be a variable across the data range you plotted and is a function of how the sensor is mounted among other things. Anyway, maybe we are all reading too much into this preliminary, and somewhat noisy, data. We'll see how things look after better mounting.
