CL5D Experiment: Cosmological Parameter Constraints from Real Observations (2025)

This dataset presents the cosmological parameter constraints from the CL5D experiment conducted from January to October 2025. The compilation aggregates current experimental measurements including tensor-to-scalar ratio (r) from BICEP/Keck, scalar spectral index (nₛ) from Planck, stochastic gravitational wave background from NANOGrav, E-mode excess measurements from ACT and SPT-3G, fractal dimension analysis from large-scale structure surveys, and entropy parameters from combined Planck and BAO data. This synthesized parameter set serves as a reference for cosmological model testing and theoretical development, representing the state of constraints as of October 2025.
