Abstract
This survey dataset is an extraction of the GOT experiment v008b. The extraction was received on tape from Socorro containing data for four GRTs plus HALCA. SC was flagged before imaging in Difmap. Fringes were found to HALCA with good SNR. An image was made and a one component model was fit to the data.
