Guide, focus/alignment system for BigBOSS

The BigBOSS experiment is a proposed DOE-NSF Stage IV dark energy survey. The all sky survey will be used to study the baryon acoustic oscillation (BAO) and growth of large scale structure from 0.2 < z < 3.5. Key to the timely success of BigBOSS is the total optical throughput of the system. The guide, focus/alignment system will provide essential pointing information, field acquisition, atmospheric monitoring and alignment corrections all used to maximize light throughput.
