New ROSAT XRT & PSPC Calibrations files in OGIP CALDB



    New ROSAT XRT and PSPC Calibration Files available in the OGIP CALDB
    ********************************************************************

XRT Calibration Files
---------------------
The following files are now available in
	caldb/data/rosat/xrt/bcf/

  xrt_v1.eff_area	- XRT Effective Area (version 1); 
			  729 energies vs 14 off-axis angles
			  (including vignetting)
			  in OGIP-standard format
			  **SUPERCEDED** by xrt_v2.eff_area
			  (Quality should set to BAD at remote CALDBs)
	
  xrt_v2.eff_area	- XRT Effective Area (version 2);
                          729 energies vs 14 off-axis angles
			  (including vignetting)
                          in OGIP-standard format 

  xrt_v1.egrid		- Standard Incident Energy Grid used for 
			  many the ROSAT XRT calibration datasets
			  729 energy bins
			  in OGIP-standard format

  xrt_v2.vignet		- XRT Vignetting factors
			  729 energies vs 14 off-axis angles

  pspcb_v1.spec_resp	- "Spectral response" for PSPCB (version 1)
			  729 energies vs 14 off-axis angles
			  consisting of the product of the
			  - XRT effective area:        xrt_v1.eff_area
			  - PSPC gas efficiency:       pspc_v1.gas_eff
			  - PSPCB window transmission: pspcb_v1.wind_trans

  pspcb_v2.spec_resp	- "Spectral response" for PSPCB (version 2)
			  729 energies vs 14 off-axis angles
			  consisting of the product of the
			  - XRT effective area:        xrt_v2.eff_area

A Spectral Response dataset for PSPCC is not yet available.

See previous ROSATCALDB message for information concerning the 
recent reorganization of the ROSAT PSPC detector response matrices.
