In this talk I have presented the data analysis results of extracting properties of halo WIMPs: the mass and the (ratios between the) spin–independent and spin–dependent couplings/cross sections on nucleons by the amidas website. Although non–standard astronomical setup has been used to generate pseudodata sets for our analyses, it has been found that, without prior information/assumption about the local density and velocity distribution of halo Dark Matter, these WIMP properties have been reconstructed with  ~5% to ≲40% deviations from the input values.
