Example of sibling patch segments from a fragmented patch source (of Fig. 39). New patch segments are displayed in shades of light blue, while previously observed patches are in dark blue. The discontinuities in longitude of the previously observed patches induce the fragmentation of this patch source. Tiles containing a blinding star are excluded from the observation, here displayed in orange. Tiles in the vicinity of an extremely bright star are also excluded (even if not containing it), as is the case of the star marked with a circle at ∼(323, −36).
