Difference of the log-likelihoods of the warp (Yusifov 2004) and no-warp models Δ ≡ ℓWARP−ℓNOWARP for the HIP2 sample.
|HIP2 subset||Nstars||Δ||σΔ||P(Δ > 0)|
|All No HIP2 binaries||838||–11.86||5.74||0.02|
|mv< 7.5 No HIP2 binaries||404||–2.29||4.21||0.29|
Notes.Results are shown for the whole sample (All, mv < 8.5) and for the bright sample (mv < 7.5). We also present the results obtained removing the stars labeled as binaries in van Leeuwen (2008). The standard deviation σΔ and the probability P(Δ > 0) are calculated using bootstrap resamples (see text).
