How are HSV values interpreted in Python?

edit

In OpenCV-Python, I understand Hue is measured in angles. For OpenCV and HSV, is Hue in radians or degrees?

Also, what are the minimum and maximum values for Saturation and Value in HSV?

Does the Min for Saturation correspond to the center core of the HSV cylinder, or is that the Max Saturation?

Does the Min Value correspond to the top of the HSV cylinder, or the black bottom?

What are the HSV values for cyan which have BGR of (255,255,0)?

I'd greatly appreciate any help I can get for my understanding of OpenCV HSV.
