Graphical Examples of Duplicate Source Rectification
The figures below show graphically the result of the duplicate source rectification procedure for a set of eight tiles in the Spring 99 release data set. Each figure shows sources centered on one tile that are drawn from either that tile (outlined in black), or the adjacent tiles (outlined in red or green). Open circles are non-duplicate sources from the central tile. Filled circles are sources. The color of the filled circle indicates from which tile the apparition marked for inclusion in the catalog is selected. Thus, in the first example from scan 100, the red circles on the eastern edge come from the tile to the west, and the green circles come from the tile to the east. The black circles are drawn from the central tile. Open squares show objects that fall outside the nominal 3-band covered edge of the central scan.
Most of the examples show the relatively simply two-scan interface. The example for scan 107 south, illustrates the behavior of the rectification algorithm in the complex boundaries between three scans. The algorithm is generalizable to large numbers of overlaps, such as will occur near the poles.
For each tile, two figures are presented. One illustrates the southern boundary and the other illustrates the northern.
