Wikipedia ma następujące informacje na temat tej współrzędnej kodowej:

In geometry, a disk (also spelled disc) is the region in a plane bounded by a circle. A disk is said to be closed if it contains the circle that constitutes its boundary, and open if it does not.
For a radius, $r$ , an open disk is usually denoted as $D_{r}$ and a closed disk is $\bar{D_{r}}$ . However in the field of topology the closed disk is usually denoted as $D^{2}$ while the open disk is $int D^{2}$ .
