Comparison of exposure calibration data, $\dot{X}\left(\text{FAC}\right)$ and exposure data computed from measurements of spectrum, $\dot{X}\left(A\right)$.

Source type	Exposure calibration (nR m2/s)	Exposure from spectrum (nR m2/s)	Ratio $\dot{\mathit{X}}\left(\mathbf{FAC}\right)/\dot{\mathit{X}}\left(\mathit{A}\right)$
Gold-marker	3.271	3.117	1.049
