Details of the Axes Parameters

The window "Details on the layer axis" shows the parameters of the layer axis, parts of which can be edited by the user (i.e. the axis identifier and the layer labels). The columns of the layer properties show the following information:

Column Contents
Index layer number
Property Label a user-defined label of the corresponding layer
Scale Parameters the parameters of the scaling equation (this equation relates the layer index to a scalable property, i.e. the wavelength)
Rev. an 'R' indicates a reverse direction of the scale (as, for example, the wave numbers in infrared spectroscopy)
Type the type of the layer
Group the spectral group (0, 1..4); layers not related to other layers always belong to group zero
