Observability Predictor 
Remarks
Alias KOI-94.04.The candidate KOI-94.04 is labelled here as KOI-94b according to the convention that increasing periods label planets b, c, d etc.
21 Sep 2012: The KOI-94 system is likely a planetary system given the measured Rossiter-McLaughlin effect for the candidate KOI-94 d (alias KOI-94.01) and the probable planet-planet eclipse for KOI-94 d and KOI-94 e (Hirano et al. 2012).
