The COS Instrument Handbook
describes the design, performance, operation, and calibration of COS. It is meant to be the principal reference manual for users of the Cosmic Origins Spectrograph. This handbook is written and maintained at STScI. While it presents the best available information about COS, tabulated parameters are likely to evolve as we learn more about its on-orbit performance.
This handbook is not meant to be the primary reference for COS data reduction or
analysis. That information is provided in the COS Data Handbook
. For quick reference, information on COS data products is provided in Chapter 11
