SearchAllSoft.com - SPC v1.0

This Sun Position Calculator will calculate the stead of the bottom and top of the SunВґs rim, sunset and daybreak time at any geographical emplacement (characterized by observational height, latitude and longitude) at any date (between 1900- 2100) and time. SPC will also argue the evenfall or when the Sun is not visible. A remit with latitudes and longitudes, and GMT+ for some major cities about the mankind is incorporated. The SunВґs stead is characterized by the elevation weight relative to the horizon and azimuth relative to the North commission. Since the observed stead of the Sun crapper be effected by the refraction of the light rays in the atmosphere (especially for miserable elevation angles), the programme gives both the real stead of the Sun (without atmospheric refraction) and the observed elevation and azimuth (when atmospheric refraction is accounted). The same remarks are valid for sunset and daybreak time. Atmospheric refraction is taken into calculate in a more realistic manner, than in other available Sun Position Calculators. We compute the refraction corrections by using a Standard Atmosphere exemplar. In put to near a realistic atmosphere profile the programme needs as input the expected temperature and pressure for an arbitrary chosen altitude. To employment and install SPC, download spc.zipper and unzip it on your computer. The directory SPC will be created, with four files in it: "SPC.exe", "LatLonGMT.chm", "SPC.ini" and "SPCHelp.chm". The file "SPC.exe" is the executable, and the other three files are databases and texts used forthwith by SPC.exe. "LatLonGMT.chm" is a database with Latitudes, Longitudes and GMT+ for some major cities and countries about he mankind, "SPCHelp.chm" is the help-file and "SPC.ini" is a file in which the programme remembers the last input parameters. The programme runs by launching "SPC.exe". Authors: Sandor Volkan-Kacso and Zoltan Neda s.
