Question (質問)

I am using SUZAKU satellite data of Her-X1 (Observation Id: 405058030, Date:01/10/2010) and followed the following procedure for GSO spectral analysis:
  1. Downloaded the GSO NXB background file using ver 2.6 (processed by caldb gptfile date:20110819) and reprocessed the GSO data through 'aepipeline' in same caldb environment.
  2. I have also checked for GPT_F and GPT_V in background and barycentric corrected source file, which I found same.
  3. And, 'hxdgsoxbpi' command is used for generating the source and background spectrum file.

The final GSO spectrum is generated by 'xspec' including the background spec file, rsp file :ae_hxd_gsohxnom_20100524.rsp, and arf file: ae_hxd_gsohxnom_crab_20100526.arf. In this spectrum, it is noticed that the background file is not subtracted well and the normalized count rate is very low. The same result is also obtained from ver 2.5 (processed by caldb gaptfile_date: 20100323) GSO-NXB file.

Here, I am attaching the both gso spectrum files with this mail as gso.pdf and gso2.pdf, please find it. Did I miss any step of analysis?, or is it related to another problem? Please check it and guide me, how to obtain the better GSO spectrum file?
