There are currently two methods in place: direct and strong-line abundances. Each uses different hardware and goes through a different series of calibrations, but are supposed to return the same data. The goal of this project is to empirically compare the data of each method to test correlation and accuracy, focusing on the nearby galaxy Messier 74.enNGC 628Messier 74Presentation
