Notes. The name and the primary reason why we rejected the galaxy from the final data sample are indicated in the second column. There was a problem with UGC 02587 because its images are clipped, so that the galaxy falls on one of the edges of the field. Thus, half of the galaxy is in one image and the other half in another. In addition, UGC 02587 has a strong dust lane and several foreground objects, so that even with a perfect match between frames by using astronomical software such as SWarp (Bertin et al. 2002), the image would not be useful for scientific purposes. We reject this galaxy for these reasons, but also because it requires different background treatment in each of the frames, which could affect the consistency of the surface brightness measurements at very faint levels, especially in the boundary region of both images.
