Survey contract - What distance from waypoint is in range to complete?

[undercoveryankee]

I have a few survey contracts to take temperature measurements near waypoints on the Mün and Minmus. I'm trying to write a kOS script that will activate the thermometer whenever I'm close enough to a waypoint.

Problem is, kOS doesn't automatically tell me whether I'm within range of a waypoint, so I need to know what distance from the waypoint I should be looking for. I found these two lines from GameData/Squad/Contracts.cfg:

MinimumTriggerRange = 500 // The minimum range to trigger waypoints on ground surveys before gravitational adjustments
MaximumTriggerRange = 15000 // The minimum range to trigger waypoints on high altitude surveys

But I'm not sure how these numbers are used in the game. Is the radius of an "in spaceflight near <waypoint>" parameter always equal to MaximumTriggerRange (15 km), or does it scale with the size of the body and/or the altitude threshold on the waypoint?

AFAIK, it scales inversely with the difficulty of the contract.

The mod for science doors exactly what you're trying to do.  It will even reset experiments if you have a scientist on board.  Love this mod as right clicking just doesn't feel like science to me so I'll just let the mod handle that.
