Calculate the -LS periodogram for the light curve EXAMPLES/2, then make 100 copies of the light curve replacing the magnitudes with Gaussian random noise, and run the -LS periodogram for each simulation. This is an example of how one might carry out Monte Carlo simulations with VARTOOLS to determine the bandwidth correction to the false alarm probability for a given light curve sampling. In practice one would want to run substantially more than 100 simulations.
