Fit a Box-shape transit to the light curve EXAMPLES/3.transit at the period of 2.12345 days. Allow for fractional transit durations between 0.01 and 0.1, and use 200 phase-bins. Set the time-zone to 0 (this only affects the BLSFixPer_fraconenight statistic. Do not output the model, but subtract the best-fit model from the light curve before passing it on to the next command (in this example, that is the final -rms command). The fittrap option causes the procedure to fit a trapezoid-shaped transit. The calls to -rms before and after -BLSFixPer show how subtracting the BLS model reduces the scatter of the light curve.
