Description
We present likelihoods to estimate upper limits on DM pair-annihilation in the Galactic centre, based on the
Cherenkov Telescope Array (CTA) consortium publication "Sensitivity of the Cherenkov Telescope Array to a
dark matter signal from the Galactic centre" [arXiv:2007.16129]. As explained in more detail in Sec. 5.2 of that
article, these likelihoods are suitable for models featuring cuspy dark matter profiles and generic gamma-ray
spectra produced from annihilating dark matter.
The four files contain likelihoods that have been derived with respect to the full CTA South baseline array layout
and the initial construction phase of CTA South. For each of these two cases, as indicated by the filename, we
provide tables with and without the inclusion of systematic uncertainties (where the former refers to the benchmark
treatment of systematic uncertainties as described in the main publication). Further, all likelihoods are based on the
benchmark analysis settings with respect to masking known bright gamma-ray sources and the adopted
interstellar emission models.
