Sorry Harry, but your celx script cannot work on my OS X version
So I created a .cel script to mark all the stars with exoplanets in my exoplanets.ssc file. I hand marked a total of 127 stars and the distribution is interesting in Celestia. Here it is (sorry, you'll have to copy-paste the code) :
{
