Dear friends, maybe some one of you got the volume "Atti del IX Seminario Nazionale di Gnomonica", the publication of the lectures happened during the annual Italian meeting of gnomonic. In my contribute I made some errors because of a bug in one of the program used to calculate the data. Not very big but errors, and I like to be right as much as I can. I made a paper (one sheet only) with corrections. If someone need it please ask me, I'll send it.
Thank you Mario --------------------------------------------------------- Mario Arnaldi Viale Leonardo, 82 48020 LIDO ADRIANO - Ravenna Italy E-Mail [EMAIL PROTECTED] 2ƒ E-Mail [EMAIL PROTECTED] Web Site http://digilander.iol.it/McArdal/index.htm ---------------------------------------------------------
