We aim (i) to obtain information about rotation state and shape of the largest members in the family and (ii) to constrain its debiased population down to couple of hundreds of meters in size. We have analyzed the up-to-date catalog of orbital elements of main belt asteroids. We evaluated the detection efficiency of Catalina Sky Survey (CSS) in regard to detections of members in the Datura family, and we have used our photometric observations and lightcurve inversion methods to determine the rotation states and shapes of the largest members of the family.
