| 2 | Position Switched - Dual Beam | For taking spectra of compact sources while keeping one beam on source for all integrations | Data Reduction Case | Data Reduction Example in IDL |
| 3 | Total Power Track | For building custom observing schemes such as On-Off observations with multiple "Ons" per "Off"; for measuring variations in continuum flux | Data Reduction Case | Data Reduction Example in IDL |
| 4 | Frequency Switched Track | For taking spectra of extended sources, or improving observing efficiency at the expense of bandwidth coverage for compact sources} | Data Reduction Case | Data Reduction Example in IDL |
| 5 | Beam Switched | No specific advantages to beam switching at this time, but the technique allows one to alternate the IF path seen by each of two feed horns at a rapid switching rate | Data Reduction Case | Data Reduction Example in IDL |
