Routing functions - EDCD/EDDI GitHub Wiki
The Route function was implemented by the late Cmdr Hoodathunk, and operates over a cube centred on your current position. It queries the EDSM database and for performance reasons, and to reduce the load on the EDSM server, this query needs to be somewhat tightly specified. Specifically it is restricted to:
(a) stations within 10000 Ls from the arrival point and
(b) a cube of 80 Ly for Technology Brokers, 40 Ly for Materials Traders and 25 Ly for Interstellar Factors.
