CXO Project Science: BND Data for Monochromators

Date: 20 Feb 1998, original release: 27 August 1997

rdb tables of Project Science's spectral analysis of the BND data taken when the monochromators were in use is available via anonymous ftp:

fht.HRF.rdb	fht.DCM.rdb
fhn.HRF.rdb	fhn.DCM.rdb
fhb.HRF.rdb	fhb.DCM.rdb
fhs.HRF.rdb	fhs.DCM.rdb
fc5.HRF.rdb	fc5.DCM.rdb

Ancillary files used in the reduction are ssd.qe (from M. McDermott, MST, from BESSY calibration) & fpc.qe (from R. Edgar, MST, 980622, from BESSY and Phase I results).

The distances along FOA are from the XRCF Source - detector distances web page or in text format.

The data tables include all the DCM and HIREFS data analyzed to date. This includes Phase I but not Phase D data (Jan 21,22,23).

These rdb tables have same info as described in the CAT Project Science Interim Report.

The following points apply:

• New fpc quantum efficiencies used, see above link to the data. fx2 is used in place of fhs for Phase I measurements.
• DCM above 8 keV (typically scans) have been re-fit using an extended range of PHA channels to properly sample the data at high channels.
• I use the stglog data to determine aperture-in-use as opposed to the previous release which used the aperlog. stglog is the more reliable.
• The W 1.774 anode scattering line is included in all HIREFS fits.
• The W 1.383 anode scattering line is not included in any HIREFS fits.
• Numerous re-fits at selected energies to include higher orders or to remove higher orders as appropriate. See Project Science Interim Report.
