The decade-long light curves of 23 lensed systems are presented for the first time. We complement our data set with other monitoring data available in the literature to measure the time delays in 18 systems, among which nine reach a relative precision better than 15% for at least one time delay. To achieve this, we developed an automated version of the curve-shifting toolbox PyCS to ensure robust estimation of the time delay in the presence of microlensing, while accounting for the errors due to the imperfect representation of microlensing. We also re-analysed the previously published time delays of RXj1131-1231 and HE0435-1223, by adding six and two new seasons of monitoring, respectively, and confirming the previous time-delay measurements. When the time delay measurement is possible, we corrected the light curves of the lensed images from their time delay and present the difference curves to highlight the microlensing signal contained in the data. To date, this is the largest sample of decade-long lens monitoring data, which is useful to measure $H_0$ and the size of quasar accretion discs with microlensing as well as to study quasar variability.</description><source format="bibcode">2020A&amp;A...640A.105M</source><referenceURL>https://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/640/A105</referenceURL><type>Catalog</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/TAP">TAP VizieR generic service</relatedResource></relationship><relationship><relationshipType>IsServedBy</relationshipType><relatedResource>Conesearch service</relatedResource></relationship><relationship><relationshipType>related-to</relationshipType><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/488/481">J/A+A/488/481 : Time delays and H0 from WFI J2033-4723 (Vuissoz+, 2008)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/536/A53">J/A+A/536/A53 : R-band light curves of HE 0435-1223 (Courbin+, 2011)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/553/A121">J/A+A/553/A121 : 2 lensed quasars light curves (Eulaers+, 2013)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/556/A22">J/A+A/556/A22 : R-band light curves of RX J1131-1231 (Tewes+, 2013)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/557/A44">J/A+A/557/A44 : Doubly lensed quasar SDSS J1001+5027 (Rathna Kumar+, 2013)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/MNRAS/465/4914">J/MNRAS/465/4914 : R-band light curves of HE 0435-1223 (Bonvin+, 2017)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/609/A71">J/A+A/609/A71 : R-band light curves of DES J0408-5359 (Courbin+ 2018)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/616/A183">J/A+A/616/A183 : R-band light curves of PG 1115+080 (Bonvin+, 2018)</relatedResource><relatedResource ivo-id="ivo://CDS.VizieR/J/A+A/629/A97">J/A+A/629/A97 : R-band light curves of WFI2033-4723 (Bonvin+, 2019)</relatedResource></relationship></content><rights>https://cds.unistra.fr/vizier-org/licences_vizier.html</rights><capability><interface xsi:type="vr:WebBrowser"><accessURL use="full">https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/640/A105</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/640/A105</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/640/A105</mirrorURL></interface></capability><capability><interface xsi:type="vs:ParamHTTP"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/640/A105</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/640/A105</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/640/A105</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface></capability><capability standardID="ivo://ivoa.net/std/TAP#aux"><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://tapvizier.cds.unistra.fr/TAPVizieR/tap</accessURL></interface></capability><capability xsi:type="cs:ConeSearch" standardID="ivo://ivoa.net/std/ConeSearch"><description>Cone search capability for table J/A+A/640/A105/stars (List of studied stars)</description><interface xsi:type="vs:ParamHTTP" role="std"><accessURL use="base">https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/640/A105/stars?</accessURL><mirrorURL title="VizieR at IUCAA: Pune, India">https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/640/A105/stars?</mirrorURL><mirrorURL title="VizieR at SAAO: SAAO, South Africa">http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/640/A105/stars?</mirrorURL><queryType>GET</queryType><resultType>text/xml+votable</resultType></interface><maxSR>180.0</maxSR><maxRecords>50000</maxRecords><verbosity>true</verbosity><testQuery><ra>12.6159167</ra><dec>-17.6692222</dec><sr>0.005555555555555556</sr></testQuery></capability><coverage><spatial>6/4615 8407 8423 16836 17510 19216 21972 22581 25480 26266 26372 26460 26489 26525 26618 27318 31690 35218 36427 36766 44673 47434 48389</spatial><footprint ivo-id="ivo://ivoa.net/std/moc">https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/640/A105?format=ascii</footprint></coverage><tableset><schema><name>default</name><table><name>J/A+A/640/A105/stars</name><description>List of studied stars</description><column><name>SName</name><description>Simbad name</description><ucd>meta.id</ucd><dataType xsi:type="vs:VOTableType" arraysize="32*">char</dataType></column><column><name>recno</name><description>Record number assigned by the VizieR team.
