cds-question@unistra.frgravitational-lensingastronomical-modelsWe report modelling follow-up of recently discovered gravitational-lens candidates in the Canada France Hawaii Telescope Legacy Survey. Lens modelling was done by a small group of specially interested volunteers from the Space Warps citizen-science community who originally found the candidate lenses. Models are categorized according to seven diagnostics indicating (a) the image morphology and how clear or indistinct it is, (b) whether the mass map and synthetic lensed image appear to be plausible, and (c) how the lens-model mass compares with the stellar mass and the abundance-matched halo mass. The lensing masses range from ~10^11^ to >10^13^M_{sun|_. Preliminary estimates of the stellar masses show a smaller spread in stellar mass (except for two lenses): a factor of a few below or above ~10^11^M_{sun}_. Therefore, we expect the stellar-to-total mass fraction to decline sharply as lensing mass increases. The most massive system with a convincing model is J1434+522 (SW 05). The two low-mass outliers are J0206-095 (SW 19) and J2217+015 (SW 42); if these two are indeed lenses, they probe an interesting regime of very low star formation efficiency. Some improvements to the modelling software (SpaghettiLens), and discussion of strategies regarding scaling to future surveys with more and frequent discoveries, are included.2018MNRAS.474.3700Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/474/3700CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/474/3700https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/474/3700http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/474/3700https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/474/3700https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/474/3700http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/474/3700GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/474/3700/table1 (Diagnostics of the selected models for each Space Warps candidate (see Section 6))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/474/3700/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/474/3700/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/474/3700/table1?GETtext/xml+votable180.050000true36.03978-10.968850.0055555555555555566/10741 10749 10751 11401 11405 11416-11418 11427 11440 11442-11446 11779 11781-11783 17493-17495 17664 17666 17674 17680-17681 17683 17687 17700 17703 19038-19039 19060 19064-19065 36606 36769-36770 36773 36781-36782 40909 40922 40931 40940 40945 40957https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/474/3700?format=asciidefaultJ/MNRAS/474/3700/table1Diagnostics of the selected models for each Space Warps candidate (see Section 6)REins?
