The Cosmic Origins Spectrograph (COS) will be installed on the Hubble Space Telescope (HST) during HST Servicing Mission 4 (SM4). COS is designed to primarily observe point sources, providing medium and low resolution spectroscopy in either of two channels, Far Ultraviolet (FUV), 1150-2050A and Near Ultraviolet (NUV), 1700-3200A. It is especially optimized for maximum FUV throughput, having only a single reflection between the HST optics and the FUV detector.
We will discuss the observations planned to provide the initial characterization of the instrument during the weeks following the HST SM4 and the subsequent calibration observations that will be needed to support science operations during HST Cycle 17. Those include: wavelength and flux calibrations, flat field measurement, thermal stability, spectral and spatial resolution, dark characteristics, complete optical alignment and target acquisition verification.
