An overview of the analysis currently being carried out to measure the Collins asymmetry. Preliminary plots are presented and compared to a previous result using a different method, which agree within error bounds, but further investigation will be necessary.

See the attached PPTX or PDF. A derivation of the error in A_ratio is also presented as a supplement to the presentation.

**Update: As per request at the jet meeting, I have zoomed in on the Y-Axis on the A_ratio plots that were presented. I have attached them as the .GIF images below
