Continuum Spectra
=================

Four 8192 channel spectra containing 50 peaks on the same average continuum level.

Spectrum		Continuum	Peak Area
			(counts)	(Counts)

Continuum-1k-1kpks	1,000		1,000
Continuum-1k-10kpks	1,000		10,000
Continuum-10k-1kpks	10,000		1,000  (Some peaks here are below the critical limit.)
Continuum-100-1kpks	100,000		1,000

The Continuum-an1 folder contains spectra in the ORTEC .an1 format. (This folder also holds the GammaVision .sdf and .lib files used in the example tests.)

The Continuum-chn folder contains spectra in the ORTEC .chn format.
The Continuum-csv folder SpecMaker output csv files listing the peaks positions and the expected number of counts in the peaks, together with the expected position and FWHM. An example follows.

The 'Continuum Info.txt' file is this document.
The 'Continuum-an1.zip' compressed file carries the an1 files and the associated .csv files.
The 'Continuum-chn.zip' compressed file carries the chn files and the associated .csv files.
The 'Continuum Assessments.zip' compressed file carries a number pdf files illustrating the use of SpecMaker in assessing the performance of CompAct, FitzPeaks and GammaVision. These files should be regarded as examples, not as definitive performance indicators. These files carry copyright restrictions and must not be reported or published elsewhere.
