XIS Non X-ray Background Estimation
2008-07-08 by the XIS team
Before Suzaku FTOOLS Version 7, the tool mk_corweighted_bgd_v1.1.pl and the data set of night Earth released from the XIS team were used to estimate the non X-ray background (NXB).
At Suzaku FTOOLS Version 7, which was a part of HEAsoft Version 6.4 released in December, 2007, the tool was upgraded to xisnxbgen and was released as one of the official FTOOLS. The NXB database was released as a part of the official Suzaku CALDB.
Now users should use xisnxbgen with the Suzaku CALDB instead of mk_corweighted_bgd_v1.1.pl to estimate the NXB. The tool mk_corweighted_bgd_v1.1.pl is now obsolete. The FTOOLS help document and the Suzaku ABC guide give detailed information about xisnxbgen.
