Possible mistake in poisson noise generation #116

Open rayson-chan opened 1 year ago

rayson-chan commented 1 year ago

When adding Poisson noise, it also introduces electronic noise in a gaussian distribution - but it uses a the np.sqrt twice on the default parameter 11. It seems there is a mistake and hopes you have some clarification. Because noise adding is the elementary function of the simulation. Thank you.

thanks for spotting this, it does look like an error. Will be fixed.
