Hello, it seems like this mod adds a bunch of duplicate/extra science experiments. The basic sub-satellite is adding duplicates of the temperature and pressure scans while the advanced sub-satellite is adding a unique magnetometer experiment, plus a camera experiment that as far as I can tell isn't used anywhere else. There's also the 2 experiments added by the mapping camera wedge which are also, again as far as I can tell, not used anywhere else, but at least these are somewhat unique and not duplicates. You can find all 6 inside the ScienceDefs.cfg file. I'm getting contracts that require these which is a bit annoying, plus I don't like seeing them in [x] Science.
I messed with the part files a little and results were promising, but my MM skills are rusty so I didn't finish the job, I just ended up renaming the parts to get rid of them entirely. If anyone wants to properly fix it, I hope this was useful.
