The filenames include the Kepler Input Calalogue (KIC) ids.
The headers contain the parameters of the trend filtering
method (see http://www.konkoly.hu/HAG/research.html).

The meaning of the columns are the followings:

COL1	Serial number (Restarts at each quarter)
COL2    Baricentric Julian date 
COL3    Flux summed up in a tailor-made aperture
COL4    Zero point shift
COL5    Scaling factor (1.0 = no scaling)
COL6    Shifted, scaled, and detrended flux
COL7    Flux value of COL6 in magnitude scale
