    111 The final panel is a strip chart showing the RA and DEC offsets from tile center determined post facto. When offsets are greater than a total of 10'', the telescope zero point should be updated. Pointing and tracking are currently excellent at the Mayall.
     111The final panel is a strip chart showing the RA and DEC offsets from tile center determined post facto. When offsets are greater than a total of 10", the telescope zero point should be updated. Pointing and tracking are currently excellent at the Mayall. **The actual telescope pointing updates should be made using output from mosstat. Thus the copilot plot may show non zero, but constant offsets.** The goal is to get the mosstat and copilot zero points to agree.
