The disclosed embodiments provide a system that facilitates the development and compilation of a software program. Second AV data result from a second encoding procedure. Detection patterns are described that possess geometric shapes susceptible to efficient decoding using probabilistic detection algorithms. Then, the subconstellation that requires the least amount of power to generate is selected as the pruned constellation for use by the transmitter. The surface oxide film of the bonding material, which is a low melting point metal, is thereby broken effectively, and highly hermetic bonding is performed.
