Table 5: Derived/estimated properties for optical dropout ERO galaxies with near-IR and Spitzer detections. Listed are the object ID (Col. 1), the photometric redshift estimate (Col. 2), the extinction (Col. 3), the type of the best fit template (Col. 4), the distance modulus corresponding to $z_{\rm phot}$ (Col. 5), the absolute $K\rm s$-band magnitude non-corrected for lensing (Col. 6), the absolute rest-frame $K\rm s$-band magnitude non-corrected for lensing (Col. 7), the estimated stellar mass (from scaling the SED fit or from $M^{\rm rest}(K\rm s)$ assuming LK/M=3.2, Col. 8), the estimated star formation rate non-corrected for lensing (Col. 9), and the age of the stellar population (Col. 10). To correct the above mentioned absolute quantities for gravitational magnification the appropriate magnification factors listed in Table 4 must be used.
