OGLE-TR-L9 does not have an entry in the catalogue of Rossiter-McLaughlin measurements.

 

OGLE-TR-L9 has been examined as part of the Homogeneous Studies of Transiting Extrasolar Planets project. The details from this work have been given below. In most instances they are the same as the physical properties given above, but in some cases the Homogeneous Studies results given below have been superseded by newer analyses. Separate statistical and systematic errorbars are given where relevant.
