Kepler issues

At breakfast, I went through with Barclay and Quintana (Ames) my list of all the effects that lead to variability in Kepler light-curves. These include intrinsic stellar variability, stellar variability from other stars that overlap the target, stellar variability transferred to the target by electronics issues. They include stellar proper motion, parallax, and aberration. They include variations in spacecraft temperature, pointing, and roll angle. And so on. The list is long! I am trying to make sure we understand what our pixel-level model covers and what it doesn't. I am spending a lot of my writing time on our data-driven pixel-level model getting the assumptions, capabilities, and limitations clearly specified.
