The LightCurve class is an extension of AstroPy's ~astropy.timeseries.TimeSeries object, which itself extends AstroPy's ~astropy.table.Table. Compared to a generic Table, LightCurve objects enforce the presence of three special data columns: ~LightCurve.time, ~LightCurve.flux, and ~LightCurve.flux_err. This enables a LightCurve object to offer a range of methods which are specific to working with flux-based time series data.
Light curves can be instantiated by passing array-like values to the time, flux, and flux_err parameters. Additional columns can be added by passing a table-like object to the data parameter.
LightCurve
Another difference with AstroPy ~astropy.table.Table is that all columns can be accessed conveniently as attributes. For example, LightCurve.time is offered as a shorthand for LightCurve["time"].
LightCurve.time LightCurve.flux LightCurve.flux_err
All meta data are stored in the meta dictionary. For convenience, meta data can be accessed as object attributes, e.g. LightCurve.sector is a short-hand for LightCurve.meta["sector"].
LightCurve.meta
LightCurve.plot LightCurve.scatter LightCurve.errorbar LightCurve.plot_river
The following methods all return a new LightCurve object.
