Description:
    Using the multi-slit LDSS-2 spectrograph on the William Herschel
    Telescope we have completed a redshift survey in the magnitude range
    22.5<B<24 which produced 73 redshifts representing a 73% complete
    sample uniformly selected from four deep fields at high galactic
    latitude. The survey extends to z>1 and includes the highest redshift
    galaxy (z=1.108) yet discovered in a field sample.

--------------------------------------------------------------------------------
Note (1): the numeric values correspond to fields:
     03.31 = 03z3_A  (B limit for 70% completeness: 24.0mag)
     10.21 = 10z2_A  (B limit for 70% completeness: 24.0mag)
     10.22 = 10z2_B  (B limit for 70% completeness: 24.0mag)
     10.23 = 10HST1  (B limit for 70% completeness: 24.0mag, and B>22.5)
     13.21 = 13z2_A  (B limit for 70% completeness: 23.3mag)
     13.22 = 13HST1  (B limit for 70% completeness: 23.5mag, and B>22.5)
     22.31 = 22z3_A  (B limit for 70% completeness: 23.0mag)
Note (2): The object's unique ID number (designated [GEC95] in SIMBAD)
     is of the form  ff.nnn , where
     ff = RA field (03, 10 etc.) and
    nnn = ID number in photometric catalogue
    (e.g. 10.288 is #288 in 10z2_Bcdd catalog)
Note (3): the value 9.999 indicates UnIDitenfied,
    and a value of 0.000 indicates a star.
Note (4): The spectrum type is
      A = Absorption line galaxy
      E = Emission line galaxy
      Q = QSO
Note (5): Equivalent width of [OII] line (3727Angstroems at rest):
          when EW=0 and e_EW>0 then e_EW represents an upper limit;
          when EW=0 and e_EW=0 then no value is known.
Note (6): the values of Q are:
     Q = 1 : certain
     Q = 2 : uncertain
     Q = 3 : no identification
     Q = 4 : dud, missing
Note (7): The following symbols are used:
     + = emission ; - = absorption;
     Missing? = no apparent signal;
     Weak = barely detected continuum;
     Featureless = well-detected continuum, but no real features

Nomenclature Notes:
     [GEC95] followed by the contents of the ID column of catalog
     is the acronym used in SIMBAD to designate the galaxies of this
     publication.
