Problem 1

1. Calcualte an expression for $\lambda_n^c$, the X-ray energy corrected for the dark current

$\lambda_n^c=\lambda_n^b-\lambda_n^d$

1. Calculate an expression for $G_n$, the X-ray attenuation due to the object's presence

$G_n = \frac{d\lambda_n^c}{dx}=-\mu (x,y_0+n * \Delta d)\lambda_n^c$
