VizieR Online Data Catalog: OSSOS. VII. TNOs complete data release (Bannister+, 2018)
Abstract
All observations were acquired with the 0.184"/pixel MegaCam imager of CFHT on Maunakea, Hawaii. The Outer Solar System Origins Survey (OSSOS) surveyed the distant solar system objects present in eight regions of sky ("blocks," each ~20deg2).
Discovery observations were made when each block of sky came to opposition, and they set the limiting magnitudes of the survey. OSSOS observed in the r-band (λ~640nm) MegaCam filters R.9601 and R.9602, which approximate the r-band Sloan Digital Sky Survey (SDSS) response, and in a "w" wide-band filter, GRI.MP9605. Considering purely the overall data set of images, the dense OSSOS cadence provided 20-60 epochs across 2-5yr, each to an r- or w-band ~3σ depth of magnitudes 24.1-25.3 across a substantial region of sky: ~170deg2 in the vicinity of the ecliptic. More than 8000 images were acquired. Bannister+ (2016, J/AJ/152/70) described the observations of the first two blocks (13AE and 13AO) in 2013-2015. We now describe the observations of the remaining six blocks, which had their discovery observations in the semesters 2013B, 2014B, 2015A, and 2015B. We also detail observations made for OSSOS with CFHT in 2014-2017 outside of the Large Program. See Section 2 for further details. (3 data files).- Publication:
