We invite interested astronomers to participate in an open discussion of instrumental and spacecraft effects and data reduction techniques for warm IRAC high precision photometry of exoplanets and brown dwarfs. The session will start with a set of short talks presenting open questions and features in obtaining the best reduction of precision light curves. Results of the first IRAC high-precision data challenge will be presented and discussed in the second half of the session.
