Package Contents

orbix.kepler.shortcuts.get_grid_solver(level='scalar', jit=False, kind='bilinear', E=True, trig=True, n_e=512, n_M=2048)

Helper function to get a grid-based solver and cache it.

Parameters:

• level –

  How the solver should be batching things.

  • ”scalar” means the inputs will be a single (M, e) pair and the output will be a single E, sinE, cosE value.

  • ”planet” will vectorize over times first and then over orbits.

    • M: (n_orbits, n_times)

    • e: (n_orbits,)

• jit – Whether to jit the solver.

• kind – The kind of solver to use, either “linear” or “bilinear”.

• E – Whether to compute the eccentric anomaly.

• trig – Whether to compute the sine and cosine of the eccentric anomaly.

• n_e – The number of eccentricity steps in the grid.

• n_M – The number of mean anomaly steps in the grid.
