Remarques sur l'utilisation des profils lunaires pour la reduction des observations d'occultations

It is shown that a rigourous determination of the argument in the limb charts of the Moon leads to a limb correction which, in some cases, may differ perceptibly from the one obtained by the traditional method. In the case of central occultations, the discrepancy may reach a maximum of 0″.9 when the Moon is near its maximum or minimum declination and introduces a statistical uncertainty of 0″.2 in the determination of the position of the Moon.
