AFMU: Auto Field-Maintenance Unit, module installable in Optional Internals
Alpha: Per round/shot damage
Convergence: The separation of hardpoints between each other. Using fixed weaponry on far apart hardpoints will make it hard or impossible to hit all at the same time. Fixed weapons do more damage than gimbaled which do more damage than turreted, but if you can't keep time on target with fixed, gimbaled is a good option.
Distributor: Refers to the Power Distributor Module found in the Core Internals of every ship
Double Banking: A technique that allows the use of two shield cells on just one heatsink without overheating. See Double Banking
Hitscan: Infinite Projectile speed (where you aim is where you hit, no delay)
Hotbanking: Using a shield cell without a heatsink. If heat damage occurs, it is expected.
Live: The current version of the game, 4.0, including "Odyssey" and "Horizons". The Live and Legacy galaxies were split in November 2022 and are no longer synchronized.
Legacy: The old version of the game, 3.8, including "Horizons Legacy". Consoles only have access to the Legacy galaxy.
RoF: Rate of Fire, if a value is given assume rounds / second.
Sustained Damage Per Second: A refined metric for measuring the damage potential of a weapon, is it also factors reload and charge times. Can also take energy delivery based on the power distributor into account.
ToT: Time on Target: The proportion of time one can spend firing a weapon compared to time needed to reposition. Some weapons rely on having high ToT to be effective.
