User Guide to the Jb95 Spectral Fitting Program

D. Generating simulated data when no experimental data exists
From the ANALYSIS OPTIONS DIALOG, uncheck the DSP STAT for all experimental data channels. From the ROTOR CALCULATIONS OPTIONS DIALOG, run iar95.exe and read the output files into any simulation channel. Depress the WRITE SIM option in the SIMULATION CONTROL DIALOG to save the simulation as a binary file. Upon entering a filename, the program will prompt you with the question: NO EXPERIMENTAL DATA -CREATE FULL SIMULATION? If answered YES, a binary file will be created based on the full simulated line set and imported into experimental channel 0. Note that this procedure will change the calibration parameters, INIT ABS FREQ and FSR, in the ANALYSIS OPTIONS DIALOG to accommodate the full simulated spectrum. Save the working file after (and perhaps before) using this option. Also note that the size of this file will depend on the frequency range covered by the simulation and the digital resolution determined from the ratio FSR/(PTS/FSR) (free spectral range and points/FSR) in the ANALYSIS OPTIONS DIALOG. To decrease the size of the binary file created, decrease the digital resolution by decreasing the PTS/FSR.
