39. Note that while the intensities seem to suggest as much as a 7% loss of intensity (113 counts on the CCD), the error on these measurements (averages of 1600 individual pixel intensities) amounts to 109 counts. There is, thus, no statistically significant decrease in the intensity over the time period in question. We do not suggest these data indicate an absence of photobleaching in this system.
