do_shotnum_intersection

bapsflib._hdf.utils.helpers.do_shotnum_intersection(shotnum: ndarray, sni_dict: Dict[str, ndarray], index_dict: Dict[str, ndarray]) → Tuple[ndarray, Dict[str, ndarray], Dict[str, ndarray]]

Calculates intersection of shotnum and all existing dataset shot numbers, shotnum[sni].

Parameters:

• shotnum – desired HDF5 shot numbers

• sni_dict – dictionary of all dataset sni arrays

• index_dict – dictionary of all dataset index arrays

Returns:

intersected and re-calculated versions of index and sni numpy arrays

Recall Array Relationship

shotnum[sni] = dset[index, shotnumkey]
