What do you expect are the major issues on observing strategy (e.g. acquisition images, object selection)?
Because a spectrum is obtained for every pixel, it is not necessary to define the region of any given object to be fed to a spectrometer before the data is acquired, and indeed, after the fact, a spatially extended set of spectra can be averaged in a weighted sum tailored to maximize the sensitivity for detection of any particular feature of interest. The major issue is simply the decision as to the mode to use from the three described in the answer to question (12), the desired spectral channel and bandpass, the spectral resolution, and the observing time.
