Abstract:
    We present the results of ISO observations with the CAM LW3 filter,
    centered at λeff=14.3µm, of 94 out of the 98 galaxies
    comprising the complete 60µm IRAS deep survey (IDS) sample in the
    north ecliptic polar region. In addition, we observed a source
    detected by IRAS at 25µm and found to have particularly interesting
    properties. Altogether, 106 sources were detected with a signal to
    noise ratio ≥3 and 69 with S/N≥5 in the 3.2'x3.2' fields centered on
    the nominal positions of IRAS sources. Sixty-five ≥3σ
    detections (49 of which at ≥5σ) are likely identifications of
    IRAS sources. Ten additional IRAS sources have possible ≥3σ
    ISOCAM counterparts. In 6 further cases, signals at the 2-3σ
    level were detected close to the IRAS position. Indications that IRAS
    sources might actually be multiple (source confusion) were found in 4
    IDS fields. On the whole, we confirm the reality of 69 to 90% of IDS
    sources. Appropriate statistical corrections for the bias affecting
    faint flux estimates were applied to ISOCAM data. Ten serendipitous
    sources were detected at ≥5σ, with S(14.3µm)≥3.5mJy. The
    corresponding areal density is consistent with that found in previous
    surveys. Finding charts for all observed fields are given.

Note (1): Notes as follows:
      2 = The source is reliably detected. Its flux, however, is highly
          uncertain due to a cosmic ray impact near the source.
      3 = The image of this source extends over the dead Col. 23; therefore
          part of its flux is lost. The given value includes a correction
          for the missing flux, based on the flux distribution in
          neighboring pixels.
      4 = Although the flux is measured at a <3σ level, the signal is
          detected at >3σ, in the brightest pixel.
      5 = Photometry based on the negative imprint produced by
          beam-switching; the positive one is at the edge of the field.
      6 = Photometry based on the negative imprint; the positive one gives
          a less significant signal (1.7±0.7mJy).
Note (2): Set to 'A', 'B', ... for the first, second, ... source detected
     in the IRAS deep field target. Source identified as [ACM2000] N-NNA in
     Simbad, e.g. source A of [HH87] 3-07 is [ACM2000] 3-07A in Simbad.
