Imaging FTS: A Different Approach to Integral Field Spectroscopy
Figure 11
(a) Spectra of the 15th magnitude stars in the field of the planetary nebula M27; from top to bottom: the central white dwarf (featureless, as expected, in this wavelength range), a solar-type star with the NaD 5890, 96 lines, and an M star showing TiO bands. (b) Spectrum of the standard horizontal branch A-star HD 74721 used to flux-calibrate the NGC 628 data cube (see above).
