Alias KOI-94.01.
The candidate KOI-94.01 is labelled here as KOI-94d according to the convention that increasing periods label planets b, c, d etc.

< b>26 Oct 2013 The 52 MEarth mass derived from TTVs for planet KOI-94 d is significantly smaller than the 106 MEarth mass derived from RV (Masuda et al. 2013)
< b>26 Oct 2013 The planet-planet eclipse PPE between KOI-94 d and e is confirmed and analysed by Masuda et al. (2013).
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).
