Our spectroscopic observations were spread across 5 nights in October and November 2004 for Cl 0412, 7 nights in December 2005 and February 2005 for MS 1008, 5 nights between May and July 2005 for MS 2137. For photometric data, we use both VLT/FORS2 and HST/ACS images. We obtained imaging of the MS 1008, MS 2137 and Cl 0412 samples in the ACS/F606W filter while we exploited existing imaging of MS 0451 in the ACS/F814W filter from the ST-ECF HST archive. Ground based images were taken in the B, V, R and I filters for the whole sample. The FORS2 filters B, V and I are close approximations to the Johnson-Cousins photometric system while the R filter is a special filter for FORS2 that is similar to the Cousins R . (5 data files).
