Overview

Randomized trial validates calculations for Euclid observables, highlighting high accuracy compared to benchmarks.

Key Points

  • This work aims to validate the Cosmology Likelihood for Observables in Euclid software by comparing its outputs with other benchmark codes.
  • Compared calculations from the CLOE software with external benchmark codes for observables in Euclid.
  • Analyzed both photometric and spectroscopic survey outputs across a range of cases.
  • Evaluated correlation functions and summary statistics for accuracy assessment.
  • All summary statistics deviated less than 0.1σ from the benchmarks.
  • Predictions remained statistically compatible with simulated data from benchmark codes.
  • Comparison of correlation function accuracy for both photometric and spectroscopic observables showed similar results.
