Description
The parameters.json file for the simulator cab seems to be busted in quite a number of places, with a few "ints" where there should be "floats" (most notably the gain parameters), and quite a few description strings seemingly mistakenly copy pasted (the gain min max parameters seemed to have the description strings for phases, or periods).
For the simms cab, the lat-lon-elv parameter is given as a list of floats in the json file, but this then ends up being passed as multiple repeated --lon-lat-elv parameters to simms. See #585 (comment) for more details. Changing the type of the lat-lon-elv parameter to a string makes it work, but providing a list of floats kind of reasonable so it might be better to find and correct the place where it is being misused.
