Each target has a single FITS file that contains the light curve timestamps and fluxes in the first FITS extension in a binary FITS table.  The timestamps are stored in MJD format in a column called "BJD".  The "BACKGROUND" column stores the final background light curve, derived using a Gaussian Process to reduce noise in the background model.  The "FLUX" column contains the raw fluxes from the aperture that results in the lowest 6.5-hour Combined Differential Photometric Precision fluxes, while the different versions of the CBV-corrected flux timeseries are available in columns called "FLUX[1-5]_CORR_[4,8]", depending on whether 4 or 8 CBVs are used.  The numbers after the FLUX column label specify which aperture was used.  So, FLUX5_CORR_4 are the raw fluxes from the fifth aperture corrected using 4 CBVs.  The column FLUX_CORR_4 is the best raw photometry (FLUX column) detrended with 4 CBVs, while FLUX_CORR_8 is the best raw photometry detrended with 8 CBVs.
