Fine FOS/FGS alignment will be determined. A TALED image in the 0.3 followed by an INT ACQ and a confirming ACQ image in the 4.3 will be obtained. Lastly, a fine ACQ/PEAK and confirming ACQ IMAGE will be taken. PASS reports will be analyzed in conjunction with the observations to allow determination of (V2,V3) positioning. The goal is to measure the precise plate scale and orientation. This will be acheived by performing a raster step and dwell sequence in the 4.3 arcsec aperture. The edges of the aperture should be avoided to prevent vignetting effects. An aperture map is required at each step of the dwell sequence. This test has to be conducted for both the RED and BLUE detectors. We will also determine the offset between the two detectors. The goal is to measure the precise aperture locations and sizes. The analysis of the observations will result in database changes to the table of aperture locations. Aperture maps of the TALEDs and an elliptical galaxy with a flat energy distribution in the nucleus which uniformly fill the apertures will be used to roughly determine the location of the apertures. Next the precise aperture locations will be detrmined by performing a raster step and dwell sequence in the FOS apertures along the edges of the apertures. An aperture map is required at each step of the dwell sequence. This test has tobe conducted for both the RED and BLUE detectors.
