# Light Curves¶

lightcurve() can be used to fit a source in a sequence of time bins.

## Examples¶

# Generate a lightcurve with two bins
lc = gta.lightcurve('sourceA', nbins=2)

# Generate a lightcurve with 1-week binning
lc = gta.lightcurve('sourceA', binsz=86400.*7.0)


## Reference/API¶

GTAnalysis.lightcurve(name, **kwargs)

Generate a lightcurve for the named source. The function will complete the basic analysis steps for each bin and perform a likelihood fit for each bin. Extracted values (along with errors) are Integral Flux, spectral model, Spectral index, TS value, pred. # of photons.

Parameters: name (str) – source name binsz (float) – Set the lightcurve bin size in seconds, default is 1 day. nbins (int) – Set the number of lightcurve bins. The total time range will be evenly split into this number of time bins. time_bins (list) – Set the lightcurve bin edge sequence in MET. When defined this option takes precedence over binsz and nbins. free_radius (float) – Free normalizations of background sources within this angular distance in degrees from the source of interest. free_sources (list) – List of sources to be freed. These sources will be added to the list of sources satisfying the free_radius selection LightCurve – Dictionary containing output of the LC analysis dict
