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.

ISR 2013-13: COS/FUV Characterization of Optical Effects at Potential Lifetime Positions
In this document we provide a summary of the analysis performed on data obtained as part of program 12678, "COS/FUV Characterization of Optical Effects". Changes to throughput, resolution and gain as a function of position were evaluated and compared to raytrace models

ISR 2014-01: Summary of the Cycle 19 COS Calibration Program
We summarize the Cycle 19 calibration program for the Cosmic Origins Spectrograph (COS) on the Hubble Space Telescope, covering the time period from November 2011 through October 2012. We give an overview of the Calibration Plan and status summaries for each of the individual proposals comprising the C19 Calibration program.
