welcome to the discovery database
We present here the public releases of a set of information coming from a set of observational surveys, all of which have detailed discovery circumstances measured and coupled to the real detections by a Survey Simulator.
1. The CFEPS Survey (from 2003-2007) was the first large sample of fully tracked and characterized detections.
2. The pathfinding study of Mike Alexandersen (MA) et al. (similar to two OSSOS sky blocks) of 2011-2012.
3. The OSSOS Survey from 2013-2018.
The 'ensemble' of these surveys has yielded more than 1000 TNOs inhabiting the outer Solar System, with highly precise orbits, and dynamical classifications. Here we provide additonal information about specific objects, a complete listing of our discoveries that can be associated to our well-measured, or characterized, detection efficiency and modelled using our Survey Simulator.
We provide the OSSOS Master File (CURRENTLY E+O+L+H blocks, with SDPM coming by end of 2018), the MA Master File, and the CFEPS Master File, which give the naming linkages between internal project names and the Minor Planet Center designations. (These OSSOS/MA/CFEPS names are critical as they provide the link to the 'block' of sky coverage in which the object was found. For each 'block' of sky coverage we provide a precise measurement of our object detection efficency as a function of object brightness and search rate.) Note that in all these files, objects beginning with uo are below the 'characterization limit' of the blocks and not part of the characterized sample (see our papers for more details on this). By the end of 2018, we will release the 'ENSEMBLE' MASTER FILE WITH ALL OSSOS+MA+CFEPS naming linkages.
In addition the CFEPS Summary file WARNING: STILL MISSING HILAT SURVEY and the OSSOS EOLH Summary file (the publicly available component of OSSOS) provide lists of all OSSOS+CFEPS detections, their orbital classification, and their barycentric orbital elements. NEED A TABLE for MA! These tables are, by far, best used in conjunction with the OSSOS Survey Simulator.
