cds-question@unistra.frquasarsphotometryThe mid-IR flux ratios FA/FB=2.84+/-0.06 of the two images of the gravitationally lensed quasar HE 1104-1805 show no wavelength dependence to within 3% across 3.6-8.0um, show no time dependence over 6 months, and agree with the broad emission-line flux ratios. This indicates that the mid-IR emission likely comes from scales large enough to be little affected by microlensing and that there is little differential extinction between the images. We measure a revised time delay between these two images of 152.2^+2.8^_-3.0_ (1sigma) days from R- and V-band data covering the years 1997-2006. This time delay indicates that the lens has an approximately flat rotation curve over scales of 1-2Re. We also observed uncorrelated variations of ~0.05mag/yr, which we attribute to microlensing of the optical emission from the accretion disk. The optical colors have also changed significantly in the sense that image A is now redder than image B, rather than bluer, as it was in 1993.2007ApJ...660..146Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/660/146CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/660/146https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/660/146http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/660/146https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/660/146https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/660/146http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/660/146GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/ApJ/660/146/table3Light Curves for HE 1104-1805Filt[BIJR HJKs] Filter usedinstr.setup;instr.filtercharrecnoRecord number assigned by the VizieR team.
