This example illustrates a basic usage of the -findblends command. The list EXAMPLES/lc_list_testblend contains two light curves as well as the x and y coordinates of each light curve. These light curves are searched for a sinusoidal variation using the -LS command. We then check for variability blends using the -findblends command. Here we consider any stars within 2 pixels of each other as potential blends. We use the period determined by -LS as the variability period for the -findblends command. We do this by giving the "fixcolumn" keyword, and then giving the name of the output column which stores the period. Running this example gives "EXAMPLES/2" as the source of the variability for both light curves since that light curve has a higher variability amplitude (in flux) than EXAMPLES/2.testblend.
