  UVES and HIRES high-resolution spectra of comet 9P/Tempel 1 are used to
investigate the impact and rotational light curves of various species with a
view toward building a simple model of the distribution and activity of the
sources. The emission by OH, NH, CN, C3, CH, C2, NH2 and OI, are analyzed, as
well as the light scattered by the dust. It is found that a simple model
reproduces fairly well the impact lightcurves of all species combining the
production of the observed molecules and the expansion of the material
throughout the slit. The rotational light curve for each species is explained
in terms of a single model with three sources.
