This software requests the user's observation location, local time, Right Ascension (RA), and Declination (DEC), then returns the Julian Date, Greenwich Mean Sidereal Time (GMST), Local Mean Sidereal Time (LMST), the azimuth, and elevation of the source. To run the software, users should download the zip file and extract its contents to the same directory. The zip file includes two files: AstroTool.fig and AstroTool.m. The main program to run is AstroTool.m. Enjoy!
