Figure 2
Sum of 4096 frames of data collected from the 72 nm latex colloid scattering. The region of data that was analyzed was between the two curves, 0.09 nm−1 < Q < 0.11 nm−1. This image shows the calculated photon positions, rather than raw pixel data. Defective regions in the CCD are masked out as shown. The large square mask at small Q (top center of the image) was used to exclude high-intensity regions from the analysis in order to avoid wasting computation cycles. The image shown used a 10 ms exposure time, and measured a sample at 293.9 K. The intensity near the center of the selected data region corresponds to approximately 8 photons pixel−1. |
