Light curve of KIC 5814635 (A1 V SiSrCrEu metals strong) based on original Kepler data (upper left panel) and Kepler data to which a Gaussian scatter of 1 mmag (upper right panel), 5 mmag (middle left panel), and 10 mmag (middle right panel) has been added. The subtle details revealed by Kepler can only be guessed after the introduction of a scatter of 1 mmag, which become totally unrecognizable as the scatter increases to 5 and 10 mmag, respectively. The same holds true for KIC 6426158 (A1 V SiSrCrEu). The details in the light curve (lower left panel) already get blurred after the introduction of a scatter of 1 mmag (lower right panel). This illustrates that the subtle details revealed by Kepler would have been lost in standard ground-based observations.
