737-800 clean stall speed including autoslats?

I searched the forum but could not find a reply to this question although I found loads of 737 vs stall/spin threads.

The manual for the -800 (from an unnamed company) shows a diagram of stick shaker and stall speeds. I wonder if the Clean diagram includes the effect of the auto slats being deployed.

A follow up if that is the case, at what AoA are those slats deployed?

A bonus question if I may... At what AoA is the 737NG stalling generally?

Please be patient with me as I'm not an aviator, just an avid x-plane user.

The autoslats will only deploy with TE flap at positions 1, 2 or 5; so I would hope the answer is no.

AoA - no idea, very few 737s have AoA indicators fitted. Whilst AoA would technically be more correct, we go by airspeed because that is what most of us are used to. Even the AFM graphs give stall speed as an IAS.

Thanks S&L!
Do you remember the pitch attitude you have at shaker activation and onset of stall?
It's not AoA but I might be able to work from that info...

I dont do them clean but at Flap 5 (with autoslat deployed of course!) it is about 16 deg nose up, with thrust levers closed and a steady decel of 1kt/sec.

Edit - PS: This is only to the stick-shaker, not the full stall.
