Pick Channels Dialog

This dialog is shown if you try and load a data file with more than two channels of data, or if the Prompt on Import item on the overlays menu is checked.

Each channel has an entry in the grid, with the minimum and maximum values displayed. To use each channel select one of:

Frequency	The frequency channel (there must be only one of these).
Intensity	An Intensity channel (there can be one or more of these).
Std Dev	A channel containing relative standard deviations, used to provide a weight for the least squares process when contour fitting. There must either be none of these, or one for each intensity channel.
Discard	The channel is discarded.

The

button sets all unused channels to "Intensity".
The
