5.3.4 Observing Mode: Spectral Scan

This mode is offered on a shared risk basis. In contrast to the other observing modes, this experimental mode targets spectral features much wider than the bandwidth (see Sect. 5.2.1) like solid state features. The problem is a good atmospheric calibration over the whole observed wavelength range. The spectrum has to pieced together from many different exposures. In Cycle 3, such an observation is being conducted. The best way to take such data and how to reduce it is still being investigated. If this observing mode is considered, please contact the instrument scientist via the SOFIA Help Desk.
