Data for: Identification of the Apollo 12 Lunar Module Ascent Stage impact site on the Moon

This image was produced by merging parts of two LROC NAC images, M129431676LC and M122353240RC, which show the linear field of streaks we describe in the paper. The images have approximately opposite illumination (morning and afternoon) so shadows and highlights caused by topography roughly cancel each other and albedo variations are enhanced. The contrast was then greatly enhanced to emphasize the pattern of streaks. The putative impact site is visible at the right edge. North is approximately at the top in this image, which may be compared with Figure 1 for location and orientation. Figure 1C is a crop of a small atrea of this image. The topographic shading does not cancel exactly so craters are still visible, allowing this image to be georeferenced if desired. As presented the image is not georeferenced.

本图像通过融合LROC NAC图像M129431676LC与M122353240RC的部分内容生成，这两幅图像展现了我们在论文中描述的线性条纹。图像的照明方向大致相反（分别为晨光与午后），因此地形所形成的阴影与高光大致相互抵消，而反照率的变化则得到强化。随后，对比度被大幅增强，以突出条纹的图案。潜在的撞击点位于图像右侧边缘。在此图像中，北方向大致位于上方，可参照图1以确定位置和方向。图1C是本图像局部区域的裁剪。由于地形阴影未能完全抵消，因此陨石坑仍然可见，使得该图像在必要时可以进行地理配准。当前呈现的图像尚未进行地理配准。
