ObservationPlanner.predict_acquisition(goal_snr, exposure_time)[source]

Predicts the acquisition distance (and approximate time) for the desired SNR.

Parameters:

  • desired_snr – The signal to noise ratio that you want to see as a float

  • exposure_time (float) – The length of the exposure in seconds

  • goal_snr (float)

Returns:

A tuple containing the time as a datetime and distance in km to the target when the SNR is met

Return type:

Tuple[datetime | None, float | None] | float
