spacevlbi.Observation.Baselines(i, spaceTelescopes, groundTelescopes, sourceRa, sourceDec, frequency, simLength, timeStep, allsky)

Calculate baselines formed by an array of a given source (or evaluated for a range of locations across the celestial sphere if allsky == 1). Baselines that couldn’t be formed due to the impact of a functional constraint are also calculated.

Parameters:

  • i (int) – Current time step, defaults to None

  • spaceTelescopes (list) – Array of SpaceTelescope objects, defaults to None

  • groundTelescopes (list) – Array of GroundTelescope objects, defaults to None

  • sourceRa (float) – Right ascension of target source in degrees, defaults to None

  • sourceDec (float) – Declination of target source in degrees, defaults to None

  • frequency (list) – Observation frequencies in Hz, defaults to None

  • simLength (int) – Simulation duration in seconds, defaults to None

  • timeStep (int) – Simulation time step in seconds, defaults to None

  • allsky (bool) – Calculate all-sky coverage? Defaults to None

Returns:

Array of SpaceTelescope objects

Return type:
