subtract_background
()¶ Subtract the background levels from each band.
The background levels are estimated using a biweight location estimator. This estimator will calculate a robust estimate of the background level for objects that have short-lived light curves, and it will return something like the median flux level for periodic or continuous light curves.
Returns: subtracted_observations – A modified version of the observations DataFrame with the background level removed. Return type: pandas.DataFrame
