Hi,

I would like to know why if we increase the value of the OFF contrast threshold (Bias_off) we end up having more OFF events instead of less. What I understand is that if we increase the threshold is going to be harder to trigger an event but in this case is the opposite.

For the ON events it works pretty intuitively, the higher the contrast threshold (Bias_on) lower is the amount of events generated. While for OFF events is the opposite, can you explain that please? 

Thanks.
