 ===  Flare  identification ===
-Quick-look light curves are used for flare identification.  Identifications of flares consists of several steps as follows:
-Light curves are smoothed by using average filtering in order to filter spikes from the electronics and fluctuations due to the on-board integer compression.
-Then, light curves acquired during the quiet sun periods are selected for background estimation.
-We take  median values and standard deviations of a certain number of data points (typically 1500 points) as the background level.
-Then the smoothed light curves are used to search for peaks.
-A flare is considered being detected if a
-peak satisfies several conditions as follows:
-* The peak counts is above 2 sigma of the background.
