The code refers to a specific entry within the DLsite ecosystem—one of Japan's largest digital marketplaces for independent creators and dōjin works .

This allows researchers to calculate the exact error of their software in millimeters.

Industrial hardware is often rated for specific temperatures or hazardous environments.
