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 Designof 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 (1s)

• 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

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

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

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!
