If a ballista was built to be used by Fine creatures, what Medium crossbow would it be equivalent to? Heavy, light, or hand?

The pf srd says ballista are essentially huge crossbows. I’d say tiny ballista are heavy crossbows, and fine ballista are two size progression below that. https://www.d20pfsrd.com/gamemastering/other-rules/siege-engines/

Ballista

A ballista is essentially a Huge heavy crossbow fixed in place. Its size makes it hard for most creatures to aim it. Thus, a Medium creature takes a -4 penalty on attack rolls when using a ballista, and a Small creature takes a -6 penalty. It takes a creature smaller than Large two full-round actions to reload the ballista after firing.

A ballista takes up a space 5 feet across.

If it is originally huge and used by medium creatures, then it wouldn't correspond to medium at all. It would correspond to a tiny heavy crossbow.

Thanks to both of you. I didn't even know they were on the srd; they're in a weird place.
