Current Performance Summary We have demonstrated – 0.4 mJy photometric uncertainty – 400 ppm null uncertainty – 32% efficiency per pointing The analysis of mean zodi-sensitivity for the current instrument performance and HOSTS sample is 11 zodi for the in-guide plan N-4

HOSTS Survey Will Inform the Design of a Future NASA Space Mission We identified 68 good LBTI targets There is great overlap between good LBTI targets and future space mission targets N-5

“HOSTS Plan Is Consistent with Science Scope” N-6 Typical Zodi Measurement Uncertainty per Star (1  ) Uses star-dependent null uncertainty, including –Null floor = 350 ppm (irreducible, 400 ppm for 7 Jy star) –Photometric null error Uses best 32 stars from the HOSTS target list –Mean uncertainty is 10.3 zodi Number Stars Observed

Science Validation Summary We have defined a list of tasks to execute over the next 6–9 months to address – Improved data acquisition approaches – Sensitivity improvements – PWV impact – Continued vibration improvement The planned performance improvements are sufficient to meet the threshold requirements – The modeled performance is not precise, and provides some level of risk to achieving the threshold performance N-7

Operation and Survey Plans N-8

LBT Is Ready to Support LBTI HOSTS Survey All LBT systems have been functioning during LBTI commissioning block – Addressed maintenance issues with adaptive optics without impact to LBTI commissioning – Worked systems-level issues with LBTI to completion – Added engineering nights prior to LBTI runs to demonstrate readiness with margin for corrective action LBT has demonstrated it is ready to support LBTI HOSTS survey N-9

Current Risk Summary N-13

LBTI Self-Assessment The LBTI project has demonstrated both the performance and the operational readiness to carry out the HOSTS survey A plan is in place to provide additional improvements to the current performance Execution of the HOSTS survey will provide an important deliverable to NASA for planning future exo-Earth missions We are excited to begin the survey!
