Data were selected when the Count rate was greater than 8 counts/s and the zenith angle was greater than 115 degrees. This detector map is for the vignetted component of HRI data, i.e. it should be used to cast effective exposure. de_corr.fits: The Dark Earth Detector Map for the ROSAT HRI ----------------------------------------------------------- This dataset was created using dark-Earth data from the SASS files by Steve Snowden (ROSAT GOF at NASA/GSFC) on 1995 Apr 12. Data were selected when the Count rate was greater than 8 counts/s and the zenith angle was greater than 115 degrees.

Please look under "GIS News".] Two new GIS response matrices (RMFs) are available via anonymous FTP in the directory: /caldb/data/asca/gis/cpf/95mar06 The files are called: gis2v4_0.rmf gis3v4_0.rmf and supersede the response matrices released on 1994 April 20 (gis2v3_1.rmf and gis3v3_1.rmf). In these previous versions, the low-energy tail of the pulse-height distribution was underestimated, causing an artificial soft-excess to appear in spectra with high absorption and low-energy photons. In the new RMFs, the low-energy response has been modified by taking account of ground calibration results and new theoretical calculations. The artificial soft-excesses disappear with the new RMFs. However, the response at energies above 4 keV has not been changed. This means that the high energy response problems noted in the "Calibration Uncertainties" (systematic residuals around 6 keV and above 8 keV) remain unsolved. But note that these residuals are about 5 per cent, and are dominated by statistical errors for sources of several counts per second or less. For the new RMFs, in common with previous versions: o The GIS RMF converts energy (keV) to output channel (PI: Pulse Invariant, i.e., gain-corrected PHA). o RTI-based background rejection is assumed. o The efficiency of the RMFs is normalized to unity: they should be used in conjunction with an ARF file which contains the XRT/GIS efficiency. o The GIS2 and GIS3 RMFs are the same except for identifying keywords in the headers.
