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.
