In the following form, you can input the correlator mode for your spectral line observation, (optionally) velocity and/or redshift for extragalactic lines, line frequency and subband bandwidth for all the spectral transitions that you want to cover in a single baseband. When submitted, the form will generate a PDF with all the setup. If you want, you can also generate the setup with an (optional) additional frequency shift of the whole baseband.
Note: There is no Doppler correction for the LSR/Heliocentric frame in TUNE. It assumes that the input frequencies/velocity are topocentric sky frequencies and optical velocity. You may use the Online Dopset Tool, and then use the Dopset frequency outputs as inputs to TUNE.
Detailed documentation on the tool is available here.
