Apollo 17 SIM Bay - Differences Explained

Much like the entire mission, Apollo 17's SIM Bay was a little different from it's J-Series predecessors.  The Subsatellite canister was replaced with the Lunar Sounder Experiment box, and the entire bottom shelf of experiments was changed.  The differences are listed in this table:

Apollo 15 & 16 experiment:
Replaced on Apollo 17 with:
Particles & Fields Subsatellite
Lunar Sounder Experiment 
(Also referred to as the Coherent Synthetic Aperture Radar or CSAR)
Gamma Ray Spectrometer
UV Spectrometer
Mass Spectrometer
Lunar Sounder Experiment Optical Recorder
Alpha & X-Ray Spectrometer
IR Scanning Radiometer
