A photometric sample of 89 LAE candidates was constructed from narrow-band data down to NB816=26.0 (AB) in a continuous 725arcmin2 area. Spectra of 39 objects satisfying the photometric selection criteria for LAEs were obtained with Subaru and Keck II Telescopes, among which 28 were confirmed LAEs, one was a nearby galaxy, and eight were unclassified. We also obtained spectra of another 24 NB816-excess objects in the field, identifying six additional LAEs. Description: We made spectroscopic observations of 63 objects selected from the NB816-detected catalog with FOCAS on the Subaru Telescope and DEIMOS on the Keck II Telescope. A total of 39 objects were observed with FOCAS in 2002 and 2004 in the multi-slit mode. Twenty-four objects among the 63 were observed with DEIMOS on UT 2004 April 23 and 24. File Summary:

Note (1): Groups as follows: a = Lyα emitters (LAEs) b = Nearby objects c = Unclear objects Note (2): Redshift. For LAEs 1215.67Å is adopted as the Lyα wavelength. Note (3): Instrument used as follows: D = DEIMOS F = FOCAS - = The nearby object 76702 was observed with FOCAS as well. We have adopted the DEIMOS spectrum with a better spectral resolution. Note (4): Magnitudes fainter than the 2σ magnitudes have been replaced with the 2σ magnitudes.
