Hi all the sundiallers ! OOOOUUUUPPS !
I forgotted to thank Daniel for his help in the problem of spherical sundials. There was so much answers that I was submerged. My English is old and I needed time to read and understand all the returned mails. But they were more than my hopes. Are you all, "ingenieur" in sundials ? Thank again for this solid help Best regards Alain MORY 47°N 7°E 500 m
