BoPlanets is a virtual planetarium, which shows the positions of the planets in the sun system relative to an observing planet, which can be selected out of the planets and the sun. The planets can be shown in various views. In the ecliptic view the Cartesian coordinates, in the equatorial view right ascension and declination, in the horizontal view azimuth and altitude of the planets relative to an observing planet are displayed. In the horizontal view the position of the observer on the observing planet can be selected out of a list of locations or directly by its longitude and latitude.
A list of features:
Download BoPlanets-V1.3-Up2.zip. Create a directory (folder) "BoPlanets". Open the zip file and go into the directory "BoPlanets-Inst". Copy the file "BoPlanets.jar", the file "guide_BoPlanets.html" and the file "orb_elem0.gif" to the directory "BoPlanets". That's it!
The BoPlanets.cmd file
BoPlanets works with Open JDK in OS/2-eCS. I have made a BoPlanets.cmd file with the following contents;
@echo off set path=[drive: java]\JAVA160ga5\bin set BEGINLIBPATH=[drive: java]\JAVA160ga5\bin set CLASSPATH= [drive: BoPlanets] cd [drive: BoPlanets]\BoPlanets java -Duser.home=[drive: BoPlanets]\BoPlanets -jar BoPlanets.jar 2>BoPlanets-bugs.txtI use 2 separate folders (directories), one for Java and one for BoPlanets with the files created by this program. The references used in the cmd file;
should be replaced with real drive letters. Edit and save the file "BoPlanets.cmd" from the distribution. This file is copied to the "BoPlanets" directory (folder). Furthermore, different paths?, adjust according to your needs.
Create a new program object. Specify the path and file name: "[drive: BoPlanets]\BoPlanets\BoPlanets.cmd". In the tabpage Session check the boxes "OS/2 window", "Running as an icon" and "Close Window to end program". In the tabpage General you can enter the name "BoPlanets". You find enclosed in the file an OS/2 icon.
Parameters / options explained
In the file you can find the above command file (all driveletters are set to C:) and an OS/2 BoPlanets icon: BoPlanets-ecs.zip.
