MR: that is a problem. let's call it "fluence-dependent" errors. AR simulated a 1% transit in a single pixel. then draws from the linearity coefficients to generate an "observed" response in the pixel. using the same linearity coefficients but with a different random draws, then tries to recover the "true" response. This reveals the error on the non-linearity correction. MR has done this work as well using Legendre polynomials, with proper variances on the coefficients. AR: then repeated these draws 1000 times, and investigate the shape of the error profile that results. Then have to repeat the work for many pixels. currently looking at 5x5 pixels. Questions:
