Notes (1) The scanned version of the Martynov (1973) paper (in Russian) is available here. This paper is about when the exact mid-transit and mid-occultation occurs on an eccentric orbit. Since the paper is hardly available, Dr. L. Szabados (Konkoly Observatory, Hungary) scanned it for me. Full reference: Martynov, D. Ya. 1973, in: V. P. Tsessevich (ed.), Eclisping Variable Stars, IPST Astrophys. Libr., Jerusalem, p. 313 BACK
