By holding Ctrl while selecting either models or channels, they can be plotted together for comparison. Models can be plotted along with other models and channels can be plotted with other channels.
It is possible to drag a channel from one station to another. If done, SPIA will check if time gates, current (within 10%), frequency and receiver position are identical. If so, the data from the two channels will be averaged, and new standard deviation will be calculated. The channel you have moved, will be deleted.
If these parameters are not equal, it will instead create a new channel within the station you drag to.
