We show that a simpler ratio -5/93, with a more accurate period of 18.6  years14, can be calculated by a 4-gear epicyclic train (Fig. 3a, Supplementary Figs. S21, S22).”now reads:“A rotation of  − 12223 for the Line of Nodes, derived from the Metonic and Saros  cycles9, could not be mechanized because of the large prime 223. We show that a simpler ratio − 593 , with a more accurate period of 18.6  years14, can be calculated by a 4-gear epicyclic train (Fig. 3a, Supplementary Figs. S21, S22).”Lastly, in the Supplementary Information 4 file, the legend for Supplementary Fig. S4,“The numbers ΨΞΒ (462) in Line 6 and ΨMΒ (442) in Line 33 are highlighted in red.”now reads:OPEN2Vol:.(1234567890)Scientific Reports |        (2021) 11:17361  | https://doi.org/10.1038/s41598-021-96382-9www.nature.com/scientificreports/“The numbers ϒΞΒ (462) in Line 6 and ϒΜΒ (442) in Line 33 are highlighted in red.”The original Supplementary Information 4 file is provided below.The original Article and accompanying Supplementary Information 4 file have been corrected.Additional informationSupplementary Information The online version contains supplementary material available at https:// doi. org/ 10. 1038/ s41598- 021- 96382-9.Open Access  This article is licensed under a Creative Commons Attribution 4.0 International License, which permits use, sharing, adaptation, distribution and reproduction in any medium or format, as long as you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons licence, and indicate if changes were made.
