Abstract:
We present the multi-wavelength properties and catalogue of the 15µm
and 1.4GHz radio sources detected in the European Large Area ISO
Survey (ELAIS) areas N1 and N2. Using the optical data from the Wide
Field Survey we use a likelihood ratio method to search for the
counterparts of the 1056 and 691 sources detected at 15µm and
1.4GHz, respectively, down to flux limits of S15=0.5mJy and
S1.4GHz=0.135mJy.
Description:
To identify the mid-IR sources with optical objects we use the data
from the Wide Field Survey (WFS, McMahon et al., 2001NewAR..45...97M 2001NewAR..45...97M).
This survey has been carried out using the Wide Field Camera (WFC) on
the 2.5-m Isaac Newton Telescope (INT) on the Observatorio del Roque
de Los Muchachos (La Palma).

Note (1): ELAIS designation:
C15_JHHMMSS.s+DDMMSS in tables1 (sources at 15um)
R20_JHHMMSS+DDMMSSA in tables2 (sources in radio at 20cm)
Note (2): Small values indicate extended objects. Objects with Class
larger than 0.8 are classified as point-like in this work.
Note (3): Optical flags as follows:
B1 = source in a gap between chips or in the edge of a chip
B3 = most likely optical identification when multiple counterparts
B4 = blank field
B6 = not specified in the paper
B7 = bright saturated star
B9 = other plausible optical identification when multiple counterparts
Note (4): Only in tables1.dat
