Abstract

Several existing interferometers have taken large V2 data sets without the use of spatial filters. The calibration of this kind of data is always seeing and alignment-dependent, and can result in significant systematic errors if several ideal calibrators are not available. I will demonstrate how high-precision unbiased estimates of V2 can still be retrieved from this kind of data by using one of several simple seeing corrections. In particular, I will demonstrate the success of these techniques on data sets from the SUSI interferometer and non-redundant masking experiments, and also discuss their limitations. One of the techniques described can also aid in the calibration of low S/N spatially-filtered data.
