Abstract

We show two samples of raw data from the Navy Prototype Optical Interferometer (NPOI), the first with a single baseline present, the second with three baselines present. We focus on the behavior of the group delay amplitude and the position of the group delay peak, and compare those quantities in the data samples to simulated data. We find that the simulations resemble the actual data when the flux level and spectral regions that were observed are realistic, and conclude that the NPOI fringe engine seems to be working properly.
