SUPERSEDED (see Section 3.13.5)

A detector redistribution matrix (only) gis$i$v3_1.rmf for each GIS, $i$ ($i$ = 2 or 3), produced by GIS Team (University of Tokyo) using gisrmf version 3.1.

• These are detector redistribution matrices. The effective area of the XRT etc have NOT be included (but see Section 3.13.7).
• There appears to be a problem with the energy energy response (above $\sim$4 keV) in these datasets which results in systematic residuals at around 6 keV and above 8 keV. These residuals are estimated to be at about the 5% level, and hence not significant for sources with several counts/s, dominated by statistical errors.
• These matrices were found to underestimate the low energy tails of the pulse-height distribution resulting in an artificial 'soft-excess' for spectra with high absorption and low energy photons. These datasets were therefore SUPERSEDED by those described in Section 3.13.5 on 1995 Mar 07.
