In order to demonstrate the capabilities of S-cam, an animation has been created of an observation of an entire eclipse of UZ For. This was created by splicing together two integrations, with the join between them near the mid-point of the eclipse. Each step in the animation corresponds to 3 seconds of actual data.
The lightcurve in the top of the plot shows the evolution of the total source intensity across the complete spectral range. In order to illustrate the energy-sensitivity of the device, however, the 36 array pixels in the lower image are first assigned colours based on the V/R ratio obtained from two energy bands (ranging from blue to red on a spectral scale), and are then assigned intensities based on the total counts in that pixel over the 3 second time period.
