Notes. This table give us an idea about the presence of methanol and/or water ices on the surface of theses objects. We took advantage of the last two columns to show the signal-to-noise ratio before and after the filtering, and in Col. 2 we show which wavelet was used to perform the filtering, where Bior is the wavelet Biorthogonal, Rbio is Reverse biorthogonal, Sym is Symlets, and Db is Daubechies. (1)The diameters shown here were taken from the survey “TNOs are cool” (http://public-tnosarecool.lesia.obspm.fr/). (2)Its believed that Triton had its origin in the trans-Neptunian region, and that it was captured by Neptune during the evolution of the solar system.
