LikeDM is a likelihood calculator of dark matter detection.
The basic function of LikeDM is to deal with the intermediate steps between the input dark matter model and the data. It enables fast computation of the likelihood of a given dark matter model (mass, cross section or decay rate, annihilation or decay yield spectrum), without digging into the details of cosmic-ray propagation, Fermi-LAT data analysis, and related astrophysical backgrounds.

The currently released version (v1.0.1) contains only the indirect ditection part, including
- the electron/positron measurements by AMS-02,
- the antiproton measurements by PAMELA, and
- the gamma-ray observations from dwarf spheroidal satellite galaxies by Fermi-LAT.
Further developments with more data, e.g., from the gamma-ray observations of the Galactic center and isotropic background, as well as the underground direct detection data, will be carried out soon.
