Assigned Member (担当者)2006-12-01 Y.TeradaName and Institute (質問者/機関)Dr.Lidia Oskinova, (Potsdam University)Question (質問)Dear HelpDesk,I have performed data reduction of HDX PIN according to the "Seven Steps to the Suzaku HXD analysis", the bkg exposure times were corrected. The recommended background files from Index of /suzaku/analysis/hxd/hxdnxb/pinnxb_ver1.2_w123. were also used. What is a correct way to produce a spectrum with subtracted background -- how was it done for the green histograms in Fig.1 in SUZAKU-MEMO-2006-42? I would like to fit a 0.2-50 keV (xis +pin) spectrum simultaneously in xspec. Thanks, Lidia Answer from(回答の文責)Suzak Help, Y.TeradaAnswer (答え)If you want to fit your spectrum data, we use XSPEC package in HEASOFT which is available from this URL.Here's an example to fit your pha file, example.pha, with XSPEC. We assume the background file name example_bgd.pha and response file, example.rsp. % xspec XSPEC> data example.pha XSPEC> back example_bgd.pha XSPEC> resp example.rsp XSPEC> cpd /xw <----- if you use X-Window-System XSPEC> plot ldata <----- plot in Channel Space XSPEC> setp energy <----- change X-axis to Energy XSPEC> plot ldata <----- plot in Channel Space XSPEC> model pow <----- put your model (pow low) XSPEC> fit XSPEC> plot ldata delchi <------ plot results For further information, please check the manual page.
