Corrections to Estimated Accretion Disk Size due to Color Correction, Disk Truncation, and Disk Wind

Abstract We consider three corrections to the disk sizes estimated at a given frequency using accretion models. They are due color correction, truncation an inner radius larger than innermost stable circular orbit, and winds, which we apply standard model. our results estimates of based on microlensing. find that these effects combined can explain long-standing problem from microlensing being those model (i.e., without accounting for above effects). In particular, increase correction with increasing temperature lead strong half-light even if this is close unity corresponding observed frequency. Our proposed formalism calculating also resolves issue discrepancies between size rate flux.
