this page doesn't work on mobile. hit the letter "s" to post a square to the feed. move pointer around on square to change the paramters of the curve.
Ramp of sine amplitude goes up across the square, and this is the response. the equation is
$$ G\left[\frac{T_N}{T} + \left(\frac{v}{2}\right)\coth{\left(\frac{v}{2}\right)}\right] $$
T is the temperature in pixels, which is set by the Y position of the mouse. The x position sets the period of the bias sweep. The amplitude of the bias sweep is set by the size of the square, and goes up to twice that, which is what puts the top of the shot noise right at the top corner of the square.
