Note on table3:
This table list m140, m220, m342, B and V magnitudes of all the stars
having either HST instrumental magnitude m140 (measured on Fig. 2 of this
paper) or B or V magnitudes available. B and V magnitudes are taken from
the list provided by Auriere, Koch-Miramond & Ortolani (1989, A&A, 204,
106) when available. For those blue straggler stars which were not measured
by these Authors, we took B and V magnitudes from Paresce et al. (1991,
Nature, 352, 297).
