cds-question@unistra.frlate-type-starsradial-velocitystellar-spectral-typesparallaxspectroscopyproper-motionsinfrared-astronomystellar-masseseffective-temperatureinfrared-photometryWe present a kinematic analysis of 152 low surface gravity M7-L8 dwarfs by adding 18 new parallaxes (including 10 for comparative field objects), 38 new radial velocities, and 19 new proper motions. We also add low- or moderate-resolution near-infrared spectra for 43 sources confirming their low surface gravity features. Among the full sample, we find 39 objects to be high-likelihood or new bona fide members of nearby moving groups, 92 objects to be ambiguous members and 21 objects that are non-members. Using this age-calibrated sample, we investigate trends in gravity classification, photometric color, absolute magnitude, color-magnitude, luminosity, and effective temperature.2016ApJS..225...10Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/225/10CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/PASP/110/863 : A Stellar Spectral Flux Library: 1150 - 25000 A (Pickles 1998)J/ApJ/564/421 : Spectra of T dwarfs.
