With a simple approximation for the magnification power spectrum at low optical depth the correction to the SBF-based luminosity distance is calculated. The results suggest the effect can be safely neglected at present but may become important for SBF-based Hubble diagrams at luminosity distances of about 1 Gpc and beyond.", "revisions": [ { "version": "v1", "updated": "2006-06-29T14:26:50.000Z" } ], "analyses": { "keywords": [ "gravitational microlensing", "systematic bias", "sbf-based distances", "magnification power spectrum", "surface brightness fluctuations" ], "tags": [ "journal article" ], "publication": { "publisher": "Wiley-Blackwell", "journal": "J.
