The minimum number of samples required to obtain the least uncertainties of determination for measurements of temperature and winds with a Fabry-Perot photoelectric spectrometer are derived. The specific cases for a spectrometer optimized for Doppler width (temperature) and Doppler shift (winds) determinations are treated where the minimum (critical) number of equidistant samples per free spectral range is found to be equal to 14 and 8, respectively. An approximate empirical criterion to derive the number of samples in terms of effective finesse N(e) has been obtained and is equal to approximately 4N(e) for practical spectrometer and source widths.
