We measure reddening as the difference\\nbetween the measured and predicted colors of a star, as derived from stellar\\nparameters from the SEGUE Stellar Parameter Pipeline (Lee et al. 2008a). We\\nachieve uncertainties of 56, 34, 25, and 29 mmag in the colors u-g, g-r, r-i,\\nand i-z, per star, though the uncertainty varies depending on the stellar type\\nand the magnitude of the star. The spectrum-based reddening measurements\\nconfirm our earlier \"blue tip\" reddening measurements (Schlafly et al. 2010,\\nS10), finding reddening coefficients different by -3%, 1%, 1%, and 2% in u-g,\\ng-r, r-i, and i-z from those found by the blue tip method, after removing a 4%\\nnormalization difference. These results prefer an R_V=3.1 Fitzpatrick (1999)\\nreddening law to O'Donnell (1994) or Cardelli et al. (1989) reddening laws. We\\nprovide a table of conversion coefficients from the Schlegel et al. (1998) maps\\nof E(B-V) to extinction in 88 bandpasses for 4 values of R_V, using this\\nreddening law and the 14% recalibration of SFD first reported by S10 and\\nconfirmed in this work.\\n","journal":"The Astrophysical Journal","year":2011,"id":3438,"datarank":11.515026852442325,"base_score":8.925055424124123,"endowment":8.925055424124123,"self_citation_contribution":1.3387583136186185,"citation_network_contribution":10.176268538823706,"self_endowment_contribution":1.3387583136186185,"citer_contribution":10.176268538823706,"corpus_percentile":88.1,"corpus_rank":1585,"citation_count":7517,"citer_count":191,"citers_with_citation_signal":191,"citers_with_endowment":191,"datacite_reuse_total":0,"is_dataset":false,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2011-08-08","authors":[{"id":36060,"name":"Douglas P.
