To All IVON MASSÉ (temporarilly auto-excluded as a member of this list) kindly sent me this message Hello Jorge, A little while ago, I posted on my web site some new pages with one about the measure of the declination by the shadow length of a gnomon. http://www.apro.fr/usr/ymasse/longomb.htm You will find the explanations of the formulas (in french but the writing of mathematical equations is universal) I hope this page will be of interest to you Best regards Yvon Yvon MASSE 7, rue des Tilleuls 95300 PONTOISE FRANCE Mél: [EMAIL PROTECTED]
