Citing CIAO in a Publication

If you are writing a paper and would like to cite the CIAO software, we recommend the following:

CIAO: Chandra's data analysis system
Fruscione et al. 2006, SPIE Proc. 6270, 62701V, D.R. Silvia & R.E. Doxsey, eds.

The specific version of CIAO and CALDB used for the analysis should be mentioned. Further guidelines are available from the Acknowledgment of Use of Chandra Resources.
