Con

Index introduced for the selection of variable stars from the OGLE database (Wozniak 2000). To calculate Con, we count the number of three consecutive data points that are brighter or fainter than 2σ and normalize the number by N − 2.

For a normal distribution and by considering just one star, Con should take values close to 0.045:

>>> fs = feets.FeatureSpace(only=['Con'])
>>> features, values = fs.extract(**lc_normal)
>>> dict(zip(features, values))
{'Con': 0.0476}
