----Messaggio originale---- Da: [email protected] Data: 15/11/2014 18.52 A: "Sundial list"<[email protected]> Ogg: Orologi Solari rev. 28.1 Dear all,I'm happy to inform you that the new 28.1 release of Orologi Solari is available for download from the usual address http://digilander.libero.it/orologi.solari/download/download_enu.html The main new feature is the addition of reflection sundials to the hour angle family of dials.As usual all the features of OS are now available for this new type of dial: all types of hour lines, simulation, lighting conditions computation, true horizon computation and use etc.Moreover to facilitate the placement of the mirror, tools similar to those already provided by Gianni Ferrari software (thanks Gianni) have been added: calculation of the position of the lightspot at desired time instants, calculation of the orientation of the mirror from one or more measurements of the coordinates of the lightspot. An original feature that I think can be very useful is to change the orientation of the mirror with the mouse (left button + shift key pressed) and to see in real time on the screen the changes in the hour lines pattern.When combined with the ability to insert a correctly sized photo of the wall behind the dial, this tool allows you to easily find the optimum orientation of the mirror. A tutoral specifically dedicated to the design and construction of reflection sundials is available at the address http://digidownload.libero.it/orologi.solari/download/riflessioneENU.pdf.I hope it can be be helpful in order to learn all the new features of the program. This new release also includes the new tables by Gianni Ferrari (thanks again Gianni) containing the mean values of the Equation of Time and of the Sun Declination for years from 2014 to 2061. Finally, minor problems have been solved and minor improvements as requested by users have been introduced. Waiting for any comments, criticisms, suggestions...my best regards. Gian Casalegno
