COS Documents

Newletters (STANs) Space Telescope Analysis Newsletters (STANs) are sent to observers via email, whenever there is news that may affect observation planning or analysis.
Instrument Handbook The Instrument Handbook is the primary guide to the characteristics and use of the instrument. It is also available in PDF format.
Data Handbook The HST Data Handbook is the primary reference for data format and analysis information.
Instrument Science Reports ISRs are technical reports written by the COS Group staff about various aspects of the instrument and data. They usually contain in depth information about a specific topic.
Calibration Workshop Papers The 2010 workshop presentations included a variety of COS-related subjects ranging from its commissioning and characterization to the most recent advances in data calibration.
220th AAS Posters COS posters presented at the 220th American Astronomical Society Conference in June 2012.
215th AAS Posters COS posters presented at the 215th American Astronomical Society Conference in January 2010.
Information Brochure May 2012 The COS Information Brochure contains an overview of the instrument's capabilities (PDF).
