Abstract:
    We present a multiwavelength catalog (15µm, R-band, K-band, and
    1.4GHz flux) plus spectroscopic identifications for 406 15µm
    sources detected in the European Large Area ISO Survey (ELAIS) region
    S1, over the flux density range 0.5<S15µm<150mJy. Three hundred
    thirty-two (∼82%) sources are optically identified down to R∼23.0.
    Spectra or bona fide stellar identifications are obtained for 290
    objects (∼88% of the optically identified sources). The areal
    coverage, mid-infrared (MIR) and optical completeness of the sample
    are discussed in order to allow statistical and evolutionary analyses.
