Summary of RMFs and ARFs

Below we summarise the uniform illumination RMFs and ARFs available for Swift X-ray analysis and their time-dependence. (See this thread for information on the position-dependent WT RMFs.) The relevant uniform-illumination, epoch-dependent RMF for a spectrum is also written to the screen in the output of the task xrtmkarf. The last column links to the relevant release note.

A summary of known calibration issues is available on the XRT digest page.
