^a Criteria used to select target list from general asteroid population, where family and cluster members are selected using hierarchical clustering (Zappalà et al. 1994,1990) and the maximum allowable $\delta v$ value, $\delta v^{\prime}$ , with respect to each family's or cluster's reference asteroid, is listed.
^b Osculating orbital element ranges for the target samples in this survey, where semimajor axis distances are in AU and inclination values are in degrees.
^c Number of unique objects observed belonging to each category.
^d Number of observations of objects belonging to each category (where multiple observations of single targets are counted independently).
^e Total number of known potential targets belonging to each category (as of 2009 April 1).
^f Includes all Themis family members.
^g Includes all Karin cluster members.
