6.6 Products of the Standard Data Processing (ROSAT)

     

During the ROSAT mission each investigator gets an output of the standard processing of his observation. Concerning the spectral analysis he can find general information in the source table (file name source.tbl) and specific results in the detailed analysis source table (file name sourceana.tbl). Both tables are described in appendix D and contain more or less the SASS result, described in the corresponding section of THE ROSAT DATA PRODUCTS GUIDE.

• The source table contains two hardness ratios defined as

  

  where A(11-41), B(52-201), C(52-90), and D(91-201) are counts summed over a fixed number of pulse height channels given in parenthesis. If a power law (PL) and/or Raymond-Smith (RS) model was fitted to the source spectrum in addition a corresponding reduced (CSQ) is given.

         

• The detailed analysis of a source delivers beside the mentioned hardness ratios HR and HR also the counts (CNT) of the corresponding channel bands A, B, C, and D together with standard errors (E_CNT). In case of spectral fitting in addition to the reduced (CSQ) the fitted parameters NH_PL, NH_RS, ALPHA, and T_RS with their standard errors E_* are tabled for a power law (PL) and Raymond-Smith (RS) model, respectively.
• For each fit performed for a source four different plots are created:
  • source + background spectrum versus energy,
  • background spectrum versus energy,
  • source spectrum with 1 error and fitted RS- and PL-spectrum versus energy,
  • corresponding residuals.
