783620H / 1013 7. ANALYSIS REPORT
P All nuclide library peaks are displayed regardless of the b30winds.ini
“Zero Area
Library Peak flag” setting.
— All analysis engines:
P If the b30winds.ini
“Unidentified Peak Summary and Library Peak Usage Format flag” parameter is set to “T” (true), the nuclide half-life (in days) is displayed under the COMMENTS header on the same line as the nuclide data, and the peak branching ratios are displayed in the right-most column before the peak flags. If this parameter is set to “F”, the nuclide half-life and branching ratios are omitted.
P If the b30winds.ini
“Use Internal TCC Library Peaks” parameter is set to “T”
(true), the nuclide peaks in this table (and throughout the analysis process) will be based on the internal TCC library including the peak list and peak order which may (and likely will) differ from the original analysis library. Additionally, any peak flags set in the library are discarded. This configuration may not generate optimal results for some applications. If this parameter is set to “F”, the peak list, peak order, and peak flags from the original library are used for analysis. Only the
Branching Ratio is adjusted for the coincidence summing correction. This configuration allows for improved optimization of the analysis results.
! The legend of Nuclide Codes shown after the nuclide name, Peak Codes shown at the far right, and Peak Flags shown after the Peak Activity are reported after this table. These are explained in the following section.
7.7.7.1. Summary of Library Peak Usage Flags
This table (Fig. 271) is displayed after the Summary of ROI Peak Usage and Summary of
Library Peak Usage sections of the report. The Nuclide and Peak Codes listed at the bottom of the table are based on flags set in the analysis library. The Peak Flags are defined as follows:
( This peak was used in the average nuclide activity calculation (even if any other symbols are displayed). For more information on the Weighted Average Nuclide Activity, see Section 6.7.1.
* The peak FW10M and FW25M were wider than the calibrated shape by more than 20% which would indicate that this might be a multiplet. However, deconvolution was not possible because only one peak was in the library.

!
This peak was in an area that was deconvoluted and the area of this component was zero or negative. The peak was then removed as a component and the deconvolution redone. This usually indicates the peak was not present or the energy calibration needs adjustment.
?
The peak FW25M is less than 80% of the calibration FW25M. This usually indicates that the peak has poor shape.
@ The peak FW25M was wider than the calibrated shape by more than 20%, but the
FWHM was within 20% of the calibrated FWHM. This indicates there might be a small peak near the main peak that may need to be included in the library.
% The 1-sigma counting error was greater than the Peak Cutoff value set on the Analysis tab.
$ This peak was identified as belonging to this nuclide, but the first non-interfered peak for this nuclide was not identified or was disqualified. This may indicate that this peak was not generated by the respective nuclide.
