Spectral Line Selection Tool

The ALMA spectral line catalogue contains the rest frequencies ofmillions of spectral line transitions that can be inspected andselected using this spectral selection tool. The tool can be launchedwith the buttons Select Lines to Observe... and Select Lines to Overlay... when defining the Spectral Setup in a ScienceGoal or via the button Line Catalogue within an SB.

On the left of the tool are a large number of filters that allow youto place various constraints on the spectral line search. The linesthat satisfy those constraints are shown in the main panel to theright of the filter selection panel. If the tool has been launchedfrom a Science Goal, lines can be selected and placed into a panelbelow this. When the tool is closed these lines will be entered intothe Science Goal's spectral window table. Please note that lines canbe selected and de-selected by double clicking on them.

The list of available transitions can also be sortedby column by clicking on the column title. A double click will causethat column to be the main sort column - an arrow will appear tosignal this. Subsequent clicks will reverse the order of sorting -the direction of the arrow will reverse. A secondary sort column canbe defined by single-clicking on a different column's title - theorder of this can also be reversed. The default sorting options are by Rest Frequency (primary sort) and by Transition (secondarysort).
