Figure 2
Mass calibrations for fitted datasets. (Top) The ratio of fitted counts normalized by incident-beam intensity divided by areal concentration and then normalized by theoretical fluorescence yield fit with a first-order polynomial. (Bottom) The fluorescence-normalized calibration curve from the first-order polynomial (from top) multiplied by the associated element's fluorescence yield to create the pseudo exponential calibration curve. The integrated (binned) normalized counts were overlaid. Because binning does not account for the entire area under a given element's fluorescence curve, the values are about ∼22% less than the values from fitting. Thus, the values were adjusted to yield the theoretical integrated counts at 100%. The inset is a close up of the 2 keV to 4 keV region.
