A conjectural and partial understanding of statistical libration indices in André-Michel Guerry’s 1864 Atlas

Abstract

Une compréhension conjecturale et partielle des indices de libration statistiques dans l'Atlas de 1864 d'André-Michel GuerryAntoine De Falguerolles I would like to extend my deepest gratitude to Michael Friendly for introducing me to the work of Guerry. I am extremely grateful to Ludovic Lebart, Gilles Palsky, Bernard Ycard, and Michael Friendly for encouraging me to write my notes on Guerry's Plate XVII. I also want to thank Brian Francis for the information on the British libraries and, of course, the two referees. All errors and false interpretations remain mine.
