We review their method of modified frequency switching and show that the way this method is used for large \\Delta n is not optimal and can lead to misinterpretation of measured spectral line parameters. Using a model of the Orion Nebula, conventional broadening theory and Monte Carlo simulation, we determine a transition-zone n = 224, ..., 241 (\\Delta n = 11, ..., 14), where measurement errors grow quickly with n and become comparable with the meas","authors_text":"J.
