SASv7.0.0 release of RGS background templates
Why RGS1_TEMPLATEBCKGND_003.CCF & RGS2_TEMPLATEBCKGND_003.CCF

· consistent use of rgsspectrum v2.6 · new BACKSCAL per channel, not per CCD node · new QUALITY per channel · more low BACKSCAL values · more 'bad' QUALITY channels · XSPEC takes no account of background QUALITY · outliers in the background-subtracted spectrum · replace BACKSCAL(QUALITY=1) with node median(BACKSCAL(QUALITY=0))
· SAS v7.0.0 PI extraction regions 90% & 95%

· 100% cross-dispersion
· 64 extensions such as X100_P095_1_8.00

RGS with SAS v7.0.0
How do you judge ? We have reached the stage for quantitative statistical tests · C-statistic RGS physical test harness · SNR 1ES0102-7219 is constant · HR1099 spectrum is bremsstrahlung continuum (and weak lines) · Procyon spectrum is lines (and weak continuum) · Crab
