Crystal Ball function
The Crystal Ball function, named after the Crystal Ball Collaboration (hence the capitalized initial letters), is a probability density function commonly used to model various lossy processes in high-energy physics. It consists of a Gaussian core portion and an exponential low-end tail, below a certain threshold. The function itself and its first derivative are both continuous.
