Small Solar System Object Platform LSST Project & Community Workshop SS blending session J. Camargo, M. Banda, L. da Costa, G. Vila Verde, R. Ogando, C. Adean, R.V. Martins, M. Assafin and the LIneA IT team – Observatório Nacional/MCTIC and LIneA – – INCT do e-Universo –
Motivation ● Study of small Solar System bodies ● Focus on the stellar occultation technique ● Focus on big data Be ready for the LSST
Basic tasks ● Metadata info download ● Identification of known Solar System bodies ● Download frames of interest ● Astrometry ● Orbit refinement ● Prediction of stellar occultations ● Observational campaign (worldwide collaboration) ● Organize/store observations ● Sizes/shapes/atmospheres/rings/etc

Comments ● Back-end codes exist! ● Procedures tested on DES images (more than 4.2M CCDs or ~67K pointings from NOV2012 to FEB2016). ● Small body search: from 6 months to less than 1 day for the above data. ● All known TNOs/Centaurs in these images went through the pipeline (Astrometry and occultation predictions to transneptunian and centaur objects observed within the dark energy survey – under internal review by the collaboration). ● Implementation of the codes in the context of the SSSO platform is ongoing (~60% implemented). http://www.linea.gov.br
