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**SUPERCEDED** by xrt_v2.eff_area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
(including obscuration)
in OGIP-standard format
PSPC Calibration Files
----------------------
The following files are now available in
caldb/data/rosat/pspc/bcf
boron_v1.trans - PSPC Boron filter transmission
729 energies
in OGIP-standard format
pspc_v1.egrid - Standard Incident Energy Grid used for
many the ROSAT PSPC calibration datasets
729 energy bins
in OGIP-standard format
pspc_v1.gas_eff - PSPC detector efficiency (gas transmission)
729 energies
in OGIP-standard format
pspcb_v1.wind_trans - PSPCB window transmission
729 energies
in OGIP-standard format
pspcc_v1.wind_trans - PSPCC window transmission
729 energies
in OGIP-standard format
The following files are now available in
caldb/data/rosat/pspc/cpf
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
in OGIP-standard format
**SUPERCEDED** by pspcb_v2.spec_resp
(Quality should set to BAD at remote CALDBs)
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
- PSPC gas efficiency: pspc_v1.gas_eff
- PSPCB window transmission: pspcc_v1.wind_trans
in OGIP-standard format
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.
