Abstract

This paper will present a number of analyses done with Stellar Intensity Interferometry (SII) data from the VERITAS Observatory. We will demonstrate the similarity between correlations generated using two different methods which are found to be highly consistent with one another. Then, we will discuss how we model and remove extraneous noise frequencies that disrupt VERITAS SII data. Furthermore, we will investigate the ADC Requirements needed to perform intensity interferometry. Finally, we will present a limb-darkened uniform disk angular diameter of $\beta$ UMa which we find to be 1.06 $\pm$ 0.04 $\pm$ 0.05 mas.
