17 Feb 2011 - Catherine's attempt to duplicate Bev's monthly XIS plots for ACIS I3 (FI) and S3 (BI). Each data point is a fit to 0.1 years worth of cold ACIS calibration source data, filtered to include only the upper corner regions like XIS and grades G02346. After some testing as to which fitting procedures were less sensitive to background variations (important for ACIS probably not as much for XIS), and robust against low signal-to-noise data, I chose to use a Gaussian plus a linear background component (mpfitfun.pro with some limits to prevent non-physical fits).

(I am also ignoring the issue of changing serial CTI. For ACIS this is negligible, but might not be for Suzaku?)

Paper appropriate figures?

I've attached the encapsulated postscript files for the figures from my HEAD2011 poster. Not sure if they follow the A&A rules but they have consistent notation with nice thick lines. They use color, but work OK in B/W as well.
