About OSSOS

All survey observations have been acquired by the Canada France Hawaii Telescope and are stored and processed using the Canadian Advanced Network For Astronomical Research. For additional public information is available from our public web site

Data Releases

Collaboration

The Teams will receive the object list for each semester's discoveries as a summary table of internal designations with orbital elements and uncertainties. At release, a typical object will have a semimajor axis uncertainty of 0.1-1%. Dynamical classification using the SSBN 2008 classification will be provided. Core will also provide access to the full astrometry and the imaging data for each detection.

Some topic teams will then wish to propose observations to other telescopes for next-semester studies of the sample; this will likely be the only time when the topic teams have a proposal advantage over the world. At the time of proposal, the ephemerides of most objects will be good to +/- < 30"; the half-year-later CFHT recovery of all objects will have dropped these uncertainties to a few arcseconds by the time P.I.-led exploitation observations occur.

Public

We aim to submit all observations of a given semester to the MPC 6 months after the end of the semester, except for the first semester (2013), which was delayed longer. This gives observers on quarterly systems a chance to propose for telescope deadlines a cycle later with no competition. It also gives the theory teams 5 months to work before the world sees the MPC release. Recovery observations will be sent as a batch to the MPC with the same time delay.

CFHT imaging becomes public a year after the end of each semester, e.g. on August 1, 2016, the 2015A CFHT imaging becomes public to the world.

Collaboration Teams

The principle contact for each team member should be their topic team's leader.

Team leaders can contact the Core.

Publications and Proposals

Survey

Observations are ongoing! Check the Survey Overview for our progress in getting & processing photons.

The project is surveying four fields in 2013-14, and a new set of four in 2015-16. For great detail, see the survey draft and the Accepted Proposal (access restricted to collaboration only).

Figures for presentations etc.

2013A

  • April 2013 preliminary field layout plot (here for reference. As in the proposal; varied very slightly from the observed location)
  • April 2013 observed plot - as the O and E fields have oppositions a month apart, the E field is shown at its 9 April moon-dark location, and the O field at its 8 May moon-dark location. The known TNOs plotted are for new moon, May 9.
  • 13AE discoveries plot - all positions for 9 April 2013

2013B

Calibration
