py_eddy_tracker.observations.groups.particle_candidate_step(t_start, contours_start, contours_end, space_step, dt, c, day_fraction=6, **kwargs)

Select particles within eddies, advect them, return target observation and associated percentages. For one time step.

Parameters:

• t_start (int) – julian day of the advection

• contours_start ((np.array(float),np.array(float))) – origin contour

• contours_end ((np.array(float),np.array(float))) – destination contour

• space_step (float) – step between 2 particles

• dt (int) – duration of advection

• c (GridCollection) – GridCollection with speed for particles

• day_fraction (int) – fraction of day

Params dict kwargs:

dict of params given to advection

Return (np.array,np.array):

return target index and percent associate
