a The survey’s construction-cost appraisal for CCAT is based on the survey’s cost, risk, and technical readiness evaluation (i.e., the cost appraisal and technical evaluation, or CATE, analysis) and project input, in FY2010 dollars.

b The survey’s appraisal of the schedule to first science is based on CATE analysis and project input.

c The risk scale used was low, medium low, medium, medium high, and high.

d The survey’s appraisal of operations costs, in FY2010 dollars, is based on project input.
