If you have used earlier versions of the response matrix generation tools, you will notice small differences between your values and the values given here. The PCA onboard electronics bin up the channels differently depending on which configuration has been requested.
Subsequent columns give the maximum energy bound for each channel.
If you are performing analysis for which the exact values of the energy boundaries are critical, or if you are analyzing data from separate layers and detectors, you should generate a response matrix for your particular dataset and examine the channel-energy information contained in the first extension of the FITS file.
