These centers all came from the flight into DEAN on Aug. 5, 1989. 
The storm was divided into 2 logical flights for processing: the
first was at 600mb and had 4 center penetrations; the second, at
900mb had 2.
This is not exactly the center file used to create DEAN89.TRK - the latter
was created from a center file augmented by satellite centers, and extended
over a time span both earlier and later than this file.
