FIG. 5.

Scatter plot of three measurements of a single device. The pulse height distributions of the two STJs are plotted on the axis together with the fitted Gaussian profiles. The average charge outputs for the entire scan are shown by stars with the model to obtain the values for and as a solid line.

Image of FIG. 6.
FIG. 6.

The measured spectral resolution (triangles) and the measured spatial resolution (squares). The modeled predictions are shown as solid lines.
