Sentences with phrase «by photometry»
(iii) Far - infrared spectroscopy of dust and ice features will address uncertainties in the mass and composition of dust in galaxies, and the contributions of supernovae to the interstellar dust budget will be quantified by photometry and monitoring of supernova remnants in nearby galaxies.

High - precision radial - velocity measurements confirm a sinusoidal variation with the period and phase predicted by the photometry, and rule out the presence of line - bisector variations that would indicate that the spectroscopic orbit is spurious.
The velocities are indeed noisy, with scatter of 30 m s ^ -1, but exhibit a period and phase consistent with the planet implied by the photometry.
