Observed α_os vs. luminosity distribution, and the one expected from a distribution of accretion disks that conforms to the observed luminosity function. The observed range in α_os is much smaller than the expected range, indicating that the UV and soft X‐ray emission mechanisms are much better correlated than expected from thin‐disk models.
