This detector is one of two windows in the mask on CCD number 1. The CCD is a virtual-phase device by Texas Instruments with two independent sections of 390 by 292 pixels and the two windows are at the 'leading' edge of each section. Pixel size is 22.35 microns square. The window in the mask is the full width of 390 pixels by several pixels and the clocking is varied to synchronize with the apparent motion of the image across the detector window. The output is thus a line of 390 pixels for each of many different positions in the image. This window is always viewing through a red filter and is the first of the four imaging detectors to 'see' an object as the field of view of the telescope sweeps across the sky. Sensitivity Description: See response curve for CCD given in Schmidt et al. (1986), Figure 9 and the reflectivity of the mirror given in Figure 7 of the same reference.
