SpecMaker

SpecMaker is a small program, based on an Excel spreadsheet, designed to create spectra with Gaussian peaks in it at known positions and with known areas so that the performance of one's spectrum analysis program can be gauged.

The program starts by creating a continuum by specifying the continuum level at the start and the end of the spectrum as specified in a text file. The program then makes a log-linear interpolation across the spectrum. As an alternative, an actual background spectrum can be loaded insted of the mathematically generated continuum. The progam then imposes statistically distributed scatter across the whole spectrum, the width of the scatter depending upon the channel count. Finally, the spectrum data is output to the required filename in the ORTEC CHN spectrum format. Numerical tests have established that, at least for all normal purposes, the scatter imposed by SpecMakeris statistically reasonable.

SpecMaker is free to all, but I would like to know who has downloaded it. For that reason I am asking users to register. At completion of registration SpecMaker.xls, will be available for download.

Full details of setting up and running SpecMaker, along with a description of how it operates can be found in the manual.

I am asking anyone who has used SpecMaker to feedback to me information about the work they have done with it. Has it been useful in checking out their spectrum analysis program? Did they find it useful? Did they have problems with SpecMaker itself? Any considered comments at all would be appreciated. To that end, I have created a SpecMaker feedback form on which users can send me that information.
