Usage

Downloading data for a specific source

data = pyLCR.getLightCurve('4FGL J0001.2-0747', cadence='daily', flux_type='photon', index_type='fixed', ts_min=4)

Note that the cadence refers to the binning timescale, with the options including 'daily', 'weekly', or 'monthly'. The flux_type refers to the units in which the flux is returned, with the options including 'photon' flux in units of photons cm^-2 s^-1 or 'energy' flux in units of MeV cm^{-2 -1}. The index_type refers to whether the spectral index of the source was 'fixed' or 'free' during the spectral fit.

Plotting data for a specific source

pyLCR.plotLightCurve(data, plotTS=True, plotIndex=True)
