Notes. The second column gives the time when the slit was positioned on the beacon. The next three columns show the ratio of the maximum beacon intensity (i.e. in the brightest pixel) to: the average intensity across the image area (Max/Ave); the median intensity of the image area (Max/Med), and the intensity corresponding to the peak of the intensity histogram (Max/Peak).
