The Y-axis selection. The same list of variables is also available for the X- and Z-axes. Here is a short description of some of non-selfexplanatory items.

• ScanNo: Sequence number of scan in total data set.
• VisSq, c, e, c/e: The squared visibility amplitude, uncalibrated, uncalibrated but corrected for non-zero diameter, calibrated and corrected for diameter, respectively.
• TripleAmp, c, e, c/e: Amplitude of triple product, with same attributes as VisSq.
• TriplePhase, c: Uncalibrated and calibrated phase of the triple product (also called closure phase).
