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.
