Nevermind, I found my answer:
This document provides rules updates for a wide selection of Forge World Tau Empireunits previously covered in early Imperial Armour books.Each unit entry indicates which Force Organisation Chart slot it may be selected as,which Codex this applies to, and the document as a whole bears the ‘Warhammer40,000’ stamp. This stamp indicates that the units are intended to be used in ‘standard’games of Warhammer 40,000, within the usual limitations of Codex selection and ForceOrganisation Charts. As with all our models these should be considered ‘official’, butowing to the fact that they may be unknown to your opponent, it’s best to make surethey are happy to play a game using Forge World models before you start
Ok, I've tried to format the copy and paste a few different ways but it's not working right. Basically they're 50 pts, AV 10/10/10, Fast Open topped, scout, and have a 4 shot markerlight.
They also reference a bunch of upgrades that don't exist anymore, like targetting arrays, I'd expect them to get updated soon.
So 100 pts would get you 8 markerlight shots, versus 99 pts would get you 9 shots with pathfinders. These are arguably a lot more delicate than the pathfinders but of course a lot more mobile (not that pathfinder really have trouble finding a target)....meh. I haven't had a chance to use the models in like 7 or 8 years.
