Spectral Line Picker

The spectral line catalogue used by the OT is the Splatalogue3.1 and the millions of spectral line transitions contained within this can be searched for and selected using the Spectral Line Picker. This appears at various points in the OT where it fulfils different functions: creating spectral windows, overlaying lines in the Visual Spectral Editor and defining rest frequencies. The OT itself contains a useful subset of the whole Splatalogue, but there is also the option to search the whole Splatalogue on-line.
