VizieR Online Data Catalog: Colors of the Outer Solar System Origins Survey (Schwamb+, 2019)

All the Colors of the Outer Solar System Origins Survey (Col-OSSOS) targets are drawn from the sample of over 800 trans-Neptunian objects (TNOs) and Centaurs (m_r=21.8-25.2mag; 3.6<H_r<14.5mag) found by the OSSOS (Bannister+ 2016, J/AJ/152/70 ; 2018ApJS..236...18B), a survey with well-characterized survey biases. OSSOS was a wide-field r-band survey with the 3.58m Canada-France-Hawaii Telescope's (CFHT) MegaPrime square-degree field-of-view (FOV) imager (MegaCam). Operating from 2013 to 2017, OSSOS searched eight 20deg² regions (blocks) of sky, at locations where resonant TNOs come to perihelion and become optimally detectable.

The Col-OSSOS sample consists of the 96 TNOs brighter than or equal to m_r=23.6 in the 13AE, 13AO, 13BL, 14BH, and 15BS OSSOS blocks. Col-OSSOS photometry for the 35 TNOs from 13BL (o3l-designated targets) and 14BH (o4h-designated targets) blocks is reported in this paper. 13BL block is a 20deg² region overlaying the invariant plane, centered at RA=0:54, DE=+3:50. 14BH block is a 21deg² region 2°-5° off the invariant plane, centered at RA=1:35, DE=+13:28.

The Gemini observations were acquired as described in Section 3.3, during 2014-2015 (under programs GN-2014B-LP-1, GN-2015A-LP-1, and GN-2015B-LP-1), with some minor exceptions described in Section 5.2. Table 3 gives a detailed summary of the GMOS-N and NIRI observations for each target TNO in g-, r-, and J-band.
