Using the "standard pair" technique of paring stars of almost nil and high extinction but otherwise of almost identical stellar parameters from the SDSS, and combing the SDSS, GALEX, 2MASS and WISE photometry ranging from the far UV to the mid-IR, we have measured dust reddening in the FUV-NUV, NUV-u, u-g, g-r, r-i, i-z, z-J, J-H, H-Ks, Ks-W1 and W1-W2 colors for thousands of Galactic stars. The measurements, together with the E(B-V) values given by Schlegel et al. (1998), allow us to derive the observed, model-free reddening coefficients for those colors. The results are compared with previous measurements and the predictions of a variety of Galactic reddening laws. We find that 1) The dust reddening map of Schlegel et al. (1998) over-estimates E(B-V) by about 14 per cent, consistent with the recent work of Schlafly et al. (2010) and Schlafly & Finkbeiner (2011); 2) All the new reddening coefficients, except those for NUV-u and u-g, prefer the R(V) = 3.1 Fitzpatrick reddening law rather than the R(V) = 3.1 CCM and O'Donnell (O'Donnell 1994) reddening laws. Using the Ks-band extinction coefficient predicted by the R(V) = 3.1 Fitzpatrick law and the observed reddening coefficients, we have deduced new extinction coefficients for the FUV, NUV, u, g, r, i, z, J, H, W1 and W2 passbands. We recommend that the new reddening and extinction coefficients should be used in the future and an update of the Fitzpatrick reddening law in the UV is probably necessary. We stress however that the FUV- and NUV-band coefficients should be used with caution given their relatively large measurement uncertainties. Finally, potential applications of the "standard pair" technique with the LAMOST Galactic surveys are discussed.

Galactic reddening in 3D from stellar photometry – an improved map (2018, methodology): “…‘pair method’, where the dust extinction vector is determined by comparing stars of the same spectral type (and therefore the same luminosity and colour) that lie behind different amounts of dust obscuration (Trumpler 1930; for more recent examples of this technique, see SF11 and Yuan et al. 2013).”
THE STELLAR POPULATION STRUCTURE OF THE GALACTIC DISK (2015, background): “…the 3D extinction maps of Marshall et al. (2006) in the inner-disk plane and Green et al. (2015) elsewhere (using AH/AKs = 1.48 and AH/E(B − V ) = 0.46; Schlafly & Finkbeiner 2011; Yuan et al. 2013); the latter is based on Pan-STARRS and 2MASS data and does not cover the entire APOGEE footprint.”
The age–metallicity structure of the Milky Way disc using APOGEE (2017, background): “…for the Milky Way MNRAS 000, 1–21 (2017) derived by Marshall et al. (2006) for the inner disk plane, combined with those for a large majority of the APOGEE footprint by (Green et al. 2015), adopting conversions AH/AKS = 1.48 and AH/E(B − V) = 0.46 (Schlafly & Finkbeiner 2011; Yuan et al. 2013).”

(2013) for optical bands produces somewhat better fits (∼ 10% smaller χ2) than the corrections based on Schlegel et al. (1998), or on Yuan et al. (2013) alone.”
The Optical to Mid-infrared Extinction Law Based on the APOGEE, Gaia DR2, Pan-STARRS1, SDSS, APASS, 2MASS, and WISE Surveys (2019, background): “Overall, our CERs are closely consistent with those derived by Schlafly et al. (2016), work (c)), who also reported the difference between their results and Yuan et al. (2013) in the CERs E(r−i)/E(i−z), E(J−H)/E(H−KS), and E(KS−W1)/E(W1−W2).”

(2013) for a 7000 K source spectrum at E(B−V ) = 0.4 mag, using the Cardelli et al. (1989) reddening law and assuming RV = 3.1.”
