The files contain the stitched light curve - including all available quarters from the 4-year duration of the original Kepler mission - for all 26 RR Lyrae star found in the background of main Kepler targets. There are 2 corresponding dat files for each star, the '*KPP ID*_.dat' files contain the raw light curve, the '*KPP ID*_normalized.dat' files contain the detrended, normalized light curves. The raw light curve files ('*_all.dat') have the following coloums: 1. Q (Number of quarter the observation was made in) 2. time [BJ-2454833] 3. flux 4. error The normalized light curve files ('*_normalized.dat') have the following coloumns: 1. Number of quarter the observation was made in 2. time [BJ-2454833] 3. normalized_flux
