New KOIs: Period v Radius 2 Green filled points indicate high SNR candidates. Open circles indicate low SNR candidates

Q1-Q16 Vetting Schedule 6 KOIs for TCERT vetting will be rolled out on a phased basis New KOIs in single systems (i.e no multi-planet systems) –~1000 objects, will appear this week, starting tomorrow. –We hope these will be completed by 24 th December New KOIs in multi systems –Includes new systems with multiple planets and new KOIs in known systems –300-600 KOIs, should appear late Jan/ early Feb Revet of long-period (>50 days) KOIs –A good sample for completeness/ abundance estimates –Might appear late March Everything else –When we get to it
7
Flux verus Centroid Vetting 7 For some KOIs we will ask you to vet the flux products only, for others we will ask you to vet both flux AND centroid products. Please check before vetting We’ll group KOIs by the kind of vetting required, and try to make it clear on the sign-up sheet The first batch you’ll see will be both flux and centroid.
8
How to get the vetting materials 8 Go to http://keplertcert.seti.org Click “PDF Signup and Checkout” Sign up for a batch of KOIs Click the link and enter the password –Username: tcert –Password: MorePlanet$ Documentation is at –http://keplertcert.seti.org/Q16/docs –Documentation is a little out of date (see next slides) –This presentation will be there too.

Other notes: 9 Remember: There must be convincing evidence for a KOI to be marked false positive: “Innocent until proven guilty” Email problem stars to kepler-tcert@nasa.gov to be discussed at the next meeting.

FP: Rolling Band 12

FP: Not Unique 14
15
FP: Transit not on target 15 X KIC position of star + OOT centroid ^ Difference Image centroid * Other nearby stars
16
Saturated, but no evidence that transit isn’t on target 16 X KIC position of star + OOT centroid ^ Difference Image centroid * Other nearby stars
17
Low signal to noise, don’t trust centroid 17 X KIC position of star + OOT centroid ^ Difference Image centroid * Other nearby stars
18
OOT position pulled by nearby star, rely on offset from KIC 18 X KIC position of star + OOT centroid ^ Difference Image centroid * Other nearby stars OOT centroid looks onto brightest star: offset from this value is meaningless

Where to find old vetting products 19 Q1Q6: –No longer available Q1Q8 –http://nexsci.caltech.edu/missions/Kepler/Science_Office/ Q1Q12 –http://nexsci.caltech.edu/missions/Kepler/Science_Office/ –http://exoplanetarchive.ipac.caltech.edu/cgi-bin/ExoTables/nph- exotbls?dataset=tce Q1Q16: –http://exoplanetarchive.ipac.caltech.edu/cgi-bin/ExoTables/nph- exotbls?dataset=tce –http://keplertcert.seti.org/
