With mid-infrared interferometry the thermal emission of disks can be spatially resolved, and the distribution and properties of the dust within can be studied. Our aim is to perform a statistical analysis on a large sample of 82 disks around low- and intermediate-mass young stars, based on mid-infrared interferometric observations. We intend to study the distribution of disk sizes, variability, and the silicate dust mineralogy. Archival mid-infrared interferometric data from the MIDI instrument on the Very Large Telescope Interferometer are homogeneously reduced and calibrated. Geometric disk models are used to fit the observations to get spatial information about the disks. An automatic spectral decomposition pipeline is applied to analyze the shape of the silicate feature. We present the resulting data products in the form of an atlas, containing N band correlated and total spectra, visibilities, and differential phases. The majority of our data can be well fitted with a continuous disk model, except for a few objects, where a gapped model gives a better match. From the mid-infrared size-luminosity relation we find that disks around T Tauri stars are generally colder and more extended with respect to the stellar luminosity than disks around Herbig Ae stars. We find that in the innermost part of the disks (r<~1au) the silicate feature is generally weaker than in the outer parts, suggesting that in the inner parts the dust is substantially more processed. We analyze stellar multiplicity and find that in two systems (AB Aur and HD 72106) data suggest a new companion or asymmetric inner disk structure. We make predictions for the observability of our objects with the upcoming Multi-AperTure mid- Infrared SpectroScopic Experiment (MATISSE) instrument, supporting the practical preparations of future MATISSE observations of T Tauri stars.2018A&A...617A..83Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/617/A83CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/617/A83https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/617/A83http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/617/A83https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/617/A83https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/617/A83http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/617/A83GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/617/A83/table1 (Overview of the sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/617/A83/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/617/A83/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/617/A83/table1?GETtext/xml+votable180.050000true52.2660131.268650.005555555555555556Associated datahttps://cdsarc.cds.unistra.fr/assocdata/?obs_collection=J/A+A/617/A836/342 862 1029 1061 1074 1113-1115 1136 1169 1539 21430 21439 21643 21677 22828 22854 22861 22873 23548-23549 23704 23727 23738 24201 24277 24279 28762 28921 30363 30366 30741 31259 32065 36956-36957 38382 39290 39753 41132 41472 42233 42429 42595 42610-42611 42644 42704 42931 42970 42972 42981 44049 44317 44379 47742 47828https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/617/A83?format=asciiInfrareddefaultJ/A+A/617/A83/table1Overview of the sampleTypeYSO type (1)src.classcharrecnoRecord number assigned by the VizieR team.
