An example 3 day lightcurve as can be found in the LCR. It spans more than 11 yr of LAT data and refers to the source at the center of Figure 2, FSRQ 4C +28.07. This lightcurve is obtained by specifying the analysis option that the spectral index of the source is free to vary. The data gap in 2018 is due to the temporary shut down of the instrument because of a solar panel anomaly.
