Description :
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 (mr=21.8-25.2mag; 3.6<Hr<14.5mag) found by the OSSOS (Bannister+ 2016, J/AJ/152/70 ; 2018ApJS..236...18B 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).The Col-OSSOS sample consists of the 96 TNOs brighter than or equal to mr=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. This catalog contains Orbital parameters and optical and near-infrared colors of the o3l and o4h Col-OSSOS TNO sample.

    Wide band filter observations with Gemini North Telescope. Our primary observing facility is the 8.1 m Frederick C. Gillett Gemini North Telescope located on Maunakea, Hawai’i. In the optical, each target was observed with the imaging mode (5.5' X 5.5' FOV) of the Gemini Multi-Object Spectrograph (GMOS; Hook et al. 2004) using the r_G0303 (λ=6300 Å, δλ=1360 Å) and g_G0301(λ=4750 Å, δλ=1540 Å) filters, similar to the SDSS r and g bands. The GMOS observations were obtained in 1×1 binning mode. This had 0."0747 pixels with the e2v deep depletion charge-coupled devices (CCDs) available in GMOS during the 2014−2016 observing semesters, and 0."0807 pixels after the 2017 installation of Hamamatsu red-sensitive CCDs. GMOS observations were dithered by 3" – 5" from exposure to exposure. For the NIR measurements, we observed with the Near-Infrared Imager (NIRI; Hodapp et al. 2003) in MKO J. NIRI observations were acquired using the f/6 camera (0."116 per pixel resolution) with a 119."9 X 119."9 FOV. NIRI observations utilized a grid dither pattern with 8" spacing between exposures to ensure accurate background measurement and removal. For both NIRI and GMOS, these instrument configurations allow the best possible characterization of the point-spread function (PSF), and hence the best knowledge of the photometric curve of growth.
