E. Serabyn et Ew. Weisstein, CALIBRATION OF PLANETARY BRIGHTNESS TEMPERATURE SPECTRA AT NEAR-MILLIMETER AND SUBMILLIMETER WAVELENGTHS WITH A FOURIER-TRANSFORM SPECTROMETER, Applied optics, 35(16), 1996, pp. 2752-2763
A medium-resolution Fourier-transform spectrometer for ground-based ob
servation of astronomical sources at near-millimeter and submillimeter
wavelengths is described. The steps involved in measuring and calibra
ting astronomical spectra are elaborated. The spectrometer is well sui
ted to planetary spectroscopy, and initial measurements of the intrins
ic brightness temperature spectra of Uranus and Neptune at wavelengths
of 1.0 to 1.5 mm are presented. (C) 1996 Optical Society of America
