Abstract:
SDF (Subaru Deep Field) line-emitting galaxies in four narrow-band
filters at low and intermediate redshifts are presented. Broadband
colors, follow-up optical spectroscopy, and multiple NB filters
are used to distinguish Hα, [OII], and [OIII] emitters at
z=0.07-1.47 to construct their LFs. These LFs are derived down to
faint magnitudes, allowing for an accurate determination of the
faint-end slope. With a large (N∼200) sample for each redshift
interval, a Schechter profile is fitted to each LF.
Description:
Deep optical imaging of the SDF (centered at RA=13:24:38.9,
DE=+27:29:25.9) has been obtained with Suprime-Cam on the 8.2m Subaru
Telescope. Five broadband (B, V, Rc, i' and z') and four narrow-band
(NB704, NB711, NB816, and NB921) images were obtained, with a total
integration time of 595, 340, 600, 801, 504, 198, 162, 600, and 899
minutes, respectively.
FOCAS observations primarily targeting NB816 and NB921 emitters were
made on 2002 June 7-10, 2003 June 5-8, and 2004 April 24-27.
DEIMOS observations were made on 2004 April 23 and 24 on Keck II.

Note (1): Flag as follows:
d = Serendipitous sources are secondary sources detected within the
DEIMOS long slits and have the appropriate NB redshift.
e = Fortuitous sources are lower priority targets for the DEIMOS
observations with the appropriate NB redshift.
Note (2): Corresponds to the NB filter that the line emission is within. Rc
band ID's are provided for FOCAS NB711 emitters and fortuitous sources.
Note (3): Flag as follows:
c = This ID is for the i' band catalog
Note (4): Flag as follows:
b = These FOCAS objects were also observed with DEIMOS. The reported
redshift is from the DEIMOS observation
Note (5): the ')' indicates a photometric between 1 and 2σ
Note (6): In units of 10-18ergs/s/cm2 = 10-21W/m2.
