#2    GOODS_ID
       Is the matched Id in the GOODS/ACS verison r1.0 catalog

#3    ORIG_ID
       Is the Id assigned to the matched objects in the original survey

#4    RA_ACS
        Is the ALPHA_J2000 of the matched object in ACS WCS

#5    DEC_ACS
        Is the DELTA_J2000 of the matched object in ACS WCS 

#6    zspec
        Spectroscopic redshift of the matched object

#7    QF

       Quality flags for redshift determination in the different surveys:
       0    VLT / FORS2 spectroscopy: Version 1.0  :
		A: Solid redshift determination
		B: likely redshift determination
		C: tentative redshift determination
       1   VIMOS VLT Deep Survey (VVDS): Version 1.0 :
		1: 50% confidence in the redshift
		2: 75% confidence in the redshift
		3: 95% confidence in the redshift
		4: 100% confidence in the redshift
		9:  Single emission line objects
       2      Szokoly et al., 2004 :
		3.0: reliable redshift determination with unambigous X-ray counterpart
		2.0: reliable redshift determination
		1.0: detection of some features (typically single narrow EL)
		0.5: hint of some spectral features
		0.0: no success
