Paper Abstract

Reliable calibration of astronomical data from large telescopes is an essential factor in obtaining high sensitivity observations for both the astronomer at the telescope and the archive researcher. A dedicated calibration unit provides an efficient and predictable method of observing calibration frames. Such a facility is being designed for the Gemini telescopes. It is required to calibrate instruments with wavelengths from the UV to the infrared, covering a broad range of both spectral and spatial resolution. We present the design of this calibration unit and the predicted performance with the 'first-light' Gemini instruments.
