Open2 and through2 figures indicated the proper calibrated mode.
The others show improper. This is because when a load is open the point is the extreme right on the smith chart irrespective of frequency. But practical systems will have slight travel from this point as no system can be made perfect open for all frequencies.
The same is valid for through however the point for through will lie exactly at the center of the smith chart.
Hope you understood.
