sweet
- exovetter.sweet.sweet(time, flux, period, epoch, duration, plot=False)[source]
Perform the SWEET test.
The SWEET test checks that the flux out of transit is not well fit by a sine curve at either the proposed orbital period, or half, or twice that. It is a good check for both variable stars and ellopsoidal variation
- Parameters:
- timefloat array
time of the observations
- fluxfloat array
relative flux normalized to zero to fit
- periodfloat
period in same units as time
- epochfloat
time of transit event in same units as time
- durationfloat
transit event duration in units of time
- Returns:
- result2d numpy array.
columns are amplitude, uncertainty and signal-to-noise. The rows are the fits at half the period, at the period, and twice the period.
Notes
It is the caller’s responsbility to ensure that the inputs are given in consistent units.
