Notes. We assumed that contact binaries are scattered around the PLC relation, parametrically expressed as (λ, μSπ, μSτ) in the log-luminosity λ vs. log-period π vs. log-effective temperature τ space. The σS parameters control the level of scatter around the relation. We modeled the background noise as though it were generated from a thick plane (λ, π, μB) with its thickness controlled by the σB parameters. We present the values of the parameters with their 1σ credible intervals.
