Abstract:
    We describe the results of a narrowband search for ultrastrong
    emission line galaxies (USELs) with EW(Hβ)≥30Å. A total of
    542 candidate galaxies are found in a one-half square degree survey
    using two ∼120Å filters centered at 8150 and 9140Å with Subaru
    SuprimeCam. Follow-up spectroscopy for randomly selected objects in
    the candidate sample with Keck II DEIMOS shows that they consist of
    [OIII] λ5007-, [OII] λ3727-, and Hα-selected strong
    emission line galaxies at intermediate redshift (z<1) and
    Lyα-emitting galaxies at high redshift (z\gl5).

Description:
    The emission-line sample was chosen from a set of narrowband images
    obtained with the SuprimeCam camera on the Subaru 8.2m telescope. The
    data were obtained in a number of runs between 2001 and 2005 under
    photometric or near-photometric conditions.

    Spectroscopic observations were obtained for 161 USELs from the sample
    using the Deep Extragalactic Imaging Multi-Object Spectrograph
    (DEIMOS) on Keck II in a series of runs between 2003 and 2006.

Global notes:

Note (G2): An entry of "-99.00 " indicates that no excess flux was
     measured, while "-99.00a" means that there was a negative flux 
     in the aperture
Note (G3): A value of -1.0000 in the redshift column means that no
     spectroscopic data were obtained for the object, 0.0000 means that
     spectra were obtained, but the object was not identified, while
     -2.0000 denotes a star
