1. open digi, recon, merit and relation files
2. Wiki Markupreads digi to create two arrays of layer end trigger bits \ [tower\]\[layer\]\[face\] , one for CalLo and one for CalHi
3. open recon and loop on clusters, then for each cluter
   1. open the corresponding crystal collection
   2. check if any crystal end has more than 100 MeV (or whatever other threshold)
   3. if any, then look if the corresponding layer end has a trigger bit set
   4. if not so, fill in a map of missing trigger bits and add 1 to a so called "cal ghost number"
4. for each cluster, the higher the ghost number, the higher the probability that it's a ghost... but it looks like that above 2, they're all ghosts.
