The first is that each.", "Image ImageDescription": "amplifier will have slightly different characteristics. It may have a slightly different gain or. a differing linearity. Reconstructing a single image from the four sub-images can be an. image processing nightmare and unless the application demands very high readout speed, most astronomers are content to wait slightly longer for an image read out through a single. amplifier. Another drawback is cost. CCDs that have all of their output amplifiers working are rare. and come at a premium price. Most CCDs are designed with multiple outputs. Even if only one of the working outputs is actually. used, the others provide valuable backups should there be for any reason an amplifier failure.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
