What is it about?
The drift trapped particle experiences, also called the bounce-averaged drift, is used in many aspects of fusion physics. The drift across the device can make it harder to sustain the desired pressures and temperatures, and as such it is important to calculate these quantities accurately. We show methods of calculating these drifts here, and include a user-friendly code that anyone can use.

Why is it important?
This documents many methods of calculating the bounce-averaged drift. Not all methods may work equally well, and some methods can be computationally costly to calculate. By investigating different methods of calculating the drifts, we show both the ups and downsides of various approaches, and we furthermore supply a code it so that future research need not construct a new code.
