Motion of the star is the major residual and this is common across targets

This means that our model will attempt to remove any signals caused by pointing changes. It's not obvious that this is what we want for K2 where this information might be useful for doing PSF photometry. For existing K1 data, this is the right thing to do and we've seen that it can be useful but it's not obvious (in detail) that this is true for K2.

Let's think.
