A full description of these files are given in the Exam 2 write-up sent to you via email. Download the following files to a subdirectory where you wish to carry out these calculations (i.e. the so-called working directory) following the directions above. Double click on each of the files listed.
IMPORTANT NOTE: Due to OIT's paranoia about security issues, files ending in either ".dat" (standard Unix data files) and ".pro" (IDL procedure and function files) will not show up on a web browser even though those files exist on the web server disk. To counteract this, I have changed the name of all ".pro" files to ".txt" files. Make sure that your downloaded IDL files have a filename suffix of ".pro" as shown on web page link below. For instance, when you click on "orbitsfinal.pro", this file must have the filename of "orbitsfinal.pro" on your computer.
|orbitsfinal.pro||IDL driver code to carry out the calculations and generate the plots.|
|orbeqnfinal.pro||Supplies ORBITSFINAL and RK4 with the derivative equations.|
|orbplot.pro||IDL procedure to creates polar plots of an orbit.|
|orbticks.pro||Determines the tick marks for orbit plots.|
Note that students will have to supply the correct coding for the differential equations in the ORBEQNFINAL function as explained in this code and on the Exam 2 write-up sent via email.
