Methods for emulation, fitting a per-pixel polynomial (y=a0+a1*x+…ak*x^k) for m measurements is provided, where x is a known independent variable (temperature, flux), and y is the pixels response). Centering and scaling of the x variable is accommodated. Additionally, a power-law can also be fit in the forward direction. For correction, a polynomial is used to drive the response to the desired, (ymed=a0+a1*y+…ak*y^k), where y is the pixels response, and ymed is the desired response.
