BoxLeastSquaresResults
(*args)[source] [edit on github]¶ Bases:
dict
The results of a BoxLeastSquares search
Attributes: - objective : string
The scalar used to optimize to find the best fit phase, duration, and depth. See
BoxLeastSquares.power()
for more information.- period : array-like or Quantity
The set of test periods.
- power : array-like or Quantity
The periodogram evaluated at the periods in
period
. Ifobjective
is:'likelihood'
: the values ofpower
are the log likelihood maximized over phase, depth, and duration, or'snr'
: the values ofpower
are the signal-to-noise with which the depth is measured maximized over phase, depth, and duration.
- depth : array-like or Quantity
The estimated depth of the maximum power model at each period.
- depth_err : array-like or Quantity
The 1-sigma uncertainty on
depth
.- duration : array-like or Quantity
The maximum power duration at each period.
- transit_time : array-like or Quantity
The maximum power phase of the transit in units of time. This indicates the mid-transit time and it will always be in the range (0, period).
- depth_snr : array-like or Quantity
The signal-to-noise with which the depth is measured at maximum power.
- log_likelihood : array-like or Quantity
The log likelihood of the maximum power model.
