This button will call list_scans to display auxilliary information about the selected scans. This information covers the scan number, star, time, station mask, and coherent/incoherent flag. The station mask has 1 for a station contributing light to the detectors, and zero for those stations which are blocked. The coherent flag is zero for incoherent scans, i.e. data taken off the fringe packet for the purpose of bias determinations.
