cds-question@unistra.frinterstellar-reddeninggalaxiesphotometryvariable-starsAccurate maps of Galactic reddening are important for a number of applications, such as mapping the peculiar velocity field in the nearby universe. Of particular concern are systematic errors which vary slowly as a function of position on the sky, as these would induce spurious bulk flow. We have compared the reddenings of Burstein & Heiles (BH, 1982, Cat. <J/AJ/87/1165>) and those of Schlegel, Finkbeiner, & Davis (1998ApJ...500..525S, SFD) to independent estimates of the reddening, for Galactic latitudes |b|>10{deg}. Our primary source of Galactic reddening estimates comes from comparing the difference between the observed B-V colors of early-type galaxies, and the predicted B-V color determined from the B-V-Mg_2_ relation. We have fitted a dipole to the residuals in order to look for large-scale systematic deviations. There is marginal evidence for a dipolar residual in the comparison between the SFD maps and the observed early-type galaxy reddenings. If this is due to an error in the SFD maps, then it can be corrected with a small (13%) multiplicative dipole term. We argue, however, that this difference is more likely to be due to a small (0.01mag) systematic error in the measured B-V colors of the early-type galaxies. This interpretation is supported by a smaller, independent data set (globular cluster and RR Lyrae stars), which yields a result inconsistent with the early-type galaxy residual dipole. BH reddenings are found to have no significant systematic residuals, apart from the known problem in the region 230{deg}<l<310{deg}, -20{deg}<b<20{deg}.1999PASP..111...57Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASP/111/57CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASP/111/57https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASP/111/57http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASP/111/57https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASP/111/57https://vizier.iucaa.in/viz-bin/votable?-source=J/PASP/111/57http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASP/111/57GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PASP/111/57/table1 (Early-type galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASP/111/57/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/PASP/111/57/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASP/111/57/table1?GETtext/xml+votable180.050000true194.83676427.887490.005555555555555556Cone search capability for table J/PASP/111/57/table3 (RR Lyrae and Abt & Golson stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASP/111/57/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/PASP/111/57/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASP/111/57/table3?GETtext/xml+votable180.050000true5.908329.3810.0055555555555555566/110 697 948 1679 1700-1701 2142 2145 2166-2167 2227 2230 2236 2251 2261 2282 2432 2622 2629 3564 4022 4075 4212 4286 4439 4447 4479 4520 4691 4762 4833 4990 5075 5182 5701 5708 6087 6093 6301 6744 6951 6963 7174 7225 7385 7518 7642 7655 7925 7961 7986 8173 8193 8195-8196 8466 8512 8519 8763 8925 9172 9217 9368 9443 9468 9471 9509 9769 9812 10203 10378-10379 10400-10401 10523-10524 10541 10569 10584 10626 10792 10802 10863 11026 11262-11263 11389 11435 11525 11791 11832 12019 12025 12632 12696 12743 12773 13332 14994 15056 15280 16488 16840 16867 16898 16923 17472 17605-17606 17612 17660 17662 17779 17982 18080 18123 18177 18184 18241 18269 18578 18747 18830 18931 18935 18964 19104 19169 19321 19432 19449 19506 19900 20020 20101 20282 20303 20742 21146 21182 22361 22644 22746 22826 22936 23088 23271 23296 24681 24732-24733 24839 24906 24920 24934 24951 25055 25100 25235 25346-25347 25383 25533 25647 25762 25768 26055 26117 26125 26131 26281 26288 26313 26413 26596 26690 26803 26894 26957 27079 27186 27208 27255 27515 27564 27604 27652 27713-27714 27718-27719 27730 27743 27765 27773 27824 27857 27874 27907 27913-27914 27936 27938 27998 28030 28037 28040 28142 28221 28249 28383 28476 28485 28495 28582 30055 30923 31054 31066 31335 31390 31415 31648 31782 31800 32239 32257 32568 32636 32663 32758 33432 34028 34098 34521 34533-34535 34540 34542 34695 34833 35222 35235 35911 35928 36152-36153 36156 36172 36247 36621 36630 36632 36781 36785 37429 37560 38129 38321 38347 38356 38621 38658 38693 38704 38842 38852-38853 38942 39035 39858 40052 40252 40294 40321 40952 41989 43214 43259 43312 43473 43503 43597 43602 43625-43627 43630 43669 43697 43700 43731 43806 43866 43891 43941 44000 44247 44627 44812 44995 45469 45636 46031 46035 46040 46042-46043 46069 46389 46568 46608 46618 46628-46629 46754 46773 46910 46987 47157 47190 47253 47383 47386 47397 47517 48160 48484 48645https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PASP/111/57?format=asciiOpticaldefaultJ/PASP/111/57/table1Early-type galaxiesrecnoRecord number assigned by the VizieR team.
