What are "Sampler Parameters"?

[Nesuhst]

DDIM eta, img2img DDIM discretize (uniform, quad), sigma churn, sigma timn, sigma noise. All found in the settings tab.

What do they do?

I would like to know as well.

Sigma min, noise, churn and eta only work on Euler, Heun and DPM2

Mixing eta and churn don't seem to work.

Sigma min doesn't appear to affect anything.
