IXO/CAT: Comparisons


IXO/CAT Comparison to Other X-ray Observatories

Data for other missions was obtained from proposal planning responses available on the web. Resolutions were derived by folding a delta function and then fitting the FWHM using diagnonal responses. Tabular data for the other missions is available here: xrayobs_performance.tbl. (Note: some similar multiple detector quantities were combined into a mean value.). The IXO/CAT tabular data is available here: ixocat_performance_D180.tbl.

Thin lines on the area and figure-of-merit plots are for the Project requirement effective area of 3000 cm^2. Tabular data for that configuration is available here: ixocat_performance_D54.tbl.

Effective areas of high-resolution X-ray spectrometers
Note: the CAT orders 1-5 and order 0+direct would be obtained simultaneously (orders 1-5 on the grating readout, zeroth+direct on the microcalorimeter).
