cds-question@unistra.frquasarsgravitational-lensingphotometryWe present new measurements of the time delays of WFI2033-4723. The data sets used in this work include 14 years of data taken at the 1.2m Leonhard Euler Swiss telescope, 13 years of data from the SMARTS 1.3m telescope at Las Campanas Observatory and a single year of high-cadence and high-precision monitoring at the MPIA 2.2m telescope. The time delays measured from these different data sets, all taken in the R-band, are in good agreement with each other and with previous measurements from the literature. Combining all the time-delay estimates from our data sets results in Dt_AB_=36.2_-0.8_^+0.7^days (2.1% precision), Dt_AC_=-23.3_-1.4_^+1.2^days (5.6%) and Dt_BC_=-59.4_-1.3_^+1.3^days (2.2%). In addition, the close image pair A1-A2 of the lensed quasars can be resolved in the MPIA 2.2m data. We measure a time delay consistent with zero in this pair of images. We also explore the prior distributions of microlensing time-delay potentially affecting the cosmological time-delay measurements of WFI2033-4723. There is however no strong indication in our measurements that microlensing time delay is neither present nor absent. This work is part of a H0LiCOW series focusing on measuring the Hubble constant from WFI2033-4723.2019A&A...629A..97Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/629/A97CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/488/481 : Time delays and H0 from WFI J2033-4723 (Vuissoz+, 2008)J/A+A/536/A53 : R-band light curves of HE 0435-1223 (Courbin+, 2011)J/A+A/553/A121 : 2 lensed quasars light curves (Eulaers+, 2013)J/A+A/556/A22 : R-band light curves of RX J1131-1231 (Tewes+, 2013)J/A+A/557/A44 : Doubly lensed quasar SDSS J1001+5027 (Rathna Kumar+, 2013)J/MNRAS/445/2677 : Peculiar velocities in 6dFGS (Springob+, 2014)J/A+A/584/A26 : Cosmography of OB stars in solar neighbourhood (Bouy+, 2015)J/MNRAS/465/4914 : R-band light curves of HE 0435-1223 (Bonvin+, 2017)J/A+A/609/A71 : R-band light curves of DES J0408-5359 (Courbin+ 2018)J/A+A/616/A183 : R-band light curves of PG 1115+080 (Bonvin+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/629/A97https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/629/A97http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/629/A97https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/629/A97https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/629/A97http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/629/A97GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/629/A97/table1Summary of the optical monitoring campaigns of WFI2033-4723FoV1Field of viewarcminphys.angSize;instr.fovfloatrecnoRecord number assigned by the VizieR team.
