My understanding, whether under US Chess or FIDE systems, is that games in rated women's events are games that are rated just like any other games between rated players. Each game is rated based on the two players' ratings and the result. The fact that it's in an all-women's tournament or not doesn't change anything.
For info on norms for women's titles, see the FIDE Handbook, at this link: https://www.fide.com/fide/handbook.html?id=174
There are many details to norms, but here (§ 1.48) is helpful. It's the performance rating someone needs to achieve in a norm-eligible event:
GM: 2600
IM: 2450
WGM: 2400
WIM: 2250
There's other requirements, like the minimum average rating of your opponents:
GM: 2380
IM: 2230
WGM: 2180
WIM: 2030
When a person plays in a women's event, are ratings affected? If so, how are the rating reconciled with open events?
And, what sort of norms are required for women's titles?
Thanks.
