What is "crank throw"? See details for more info about Qn.?

I got this piece of information regarding bore stroke ratio of the engine - "The bore is the diameter of the cylinder and the stroke is the length that piston travels, which is generated when pistons upmost and downmost positions are compared, which is twice the crank throw."

I am wondering what "crank throw" is. Please help out? Thanks!

I believe it is the radius of the crankshaft (i.e. from the center of the shaft to the bottom of the rods).

The distance from the center line of the crankshaft to the center line of the big end of the connecting rod.
