PoGOLite (Polarised Gamma-Ray Observer Lite) is a balloon borne experiment meant to measure the polarisation of the electromagnetic radiation from specic astrophysical objects. The main target of interest for PoGOLite is the Crab pulsar. A considerable particle background was recorded during the short flight of PoGOLite in July 2011. In order to further study the particle background before the relaunch of PoGOLite, a smaller experiment named PoGOLino was initiated. For both experiments, methods to increase the signal to noise ratio in the data collected are important. The aim of this project has been to propose new methods for increasing the signal to noise ratio in collected data, and quantitatively compare them with the previous methods. On a data sample where the original ratio of signal to noise was 0.1, the prior methods were able to increase the ratio to 1.13. A signal to noise ratio of 1.98 was achieved on the same data sample, when executing two algorithms developed during the course of this project in sequence.
