我们描述了一个大面积的黄道调查，旨在评估明亮的柯伊伯带天体的天空平面表面密度。我们使用8192 × 8192像素的CCD马赛克图像51.5度2到50%的检测阈值红等mR = 22.5。在调查中发现了13个新的柯伊伯带天体，包括一些最亮的，可能是最大的已知天体。我们使用蒙特卡罗模型来评估观测偏差在我们的调查中的影响，并检查(1)柯伊伯带中明亮物体的大小分布，(2)在大半径处大小分布中可能存在的截断，(3)冥王星与非共振（“经典”）柯伊伯带天体的内在比，(4)在3:2和2:1平均运动共振中人口的内在比，以及(5)柯伊伯带的径向范围。
We describe a large-area ecliptic survey designed to assess the sky-plane surface density of bright Kuiper Belt objects. We used an 8192 × 8192 pixel CCD mosaic to image 51.5 deg2 to a 50% detection threshold red magnitude mR = 22.5. Thirteen new Kuiper Belt objects were identified in the survey, including some of the brightest and, presumably, largest known examples. We use Monte Carlo models to assess the effects of observational bias in our survey and to examine (1) the size distribution of bright objects in the Kuiper Belt, (2) the possible existence of a cutoff in the size distribution at large radii, (3) the intrinsic ratio of Plutinos to nonresonant ("classical") Kuiper Belt objects, (4) the intrinsic ratio of populations in the 3:2 and 2:1 mean motion resonances, and (5) the radial extent of the Kuiper Belt.
