HST Data Handbook for COS

How to Use this Handbook

---

This handbook is designed to help users manipulate, process, and analyze data from the Cosmic Origins Spectrograph (COS) which will be installed on the Hubble Space Telescope (HST) during the 2009 servicing mission (SM4). It is designed for users familiar with HST data but new to COS. Users who wish to find more general information including instructions for retrieving data from the HST archive, a description of HST file formats, and a discussion of PyRAF/IRAF/STSDAS software for displaying and processing these data, are referred to Part I, the Introduction to the HST Data Handbook.

For detailed information on the capabilities of the instrument, and how to plan observations, users should refer to the COS Instrument Handbook. For further information and timely updates, users should consult the COS Web page (http://www.stsci.edu/hst/cos), especially the Document Archive link. In particular, the STScI Analysis Newsletters (STANs) highlight changes in code and calibration procedures and provide other instrument-related news. The Instrument Science Reports (ISRs) present in-depth characterizations of the instrument and detailed explanations of calibration code and procedures.

The current edition of the COS Data Handbook was completed in early 2009. At present, preparations are being made for Servicing Mission 4 to HST, which includes installation of COS.
