ISOPHOT 95 µm observations in the Lockman Hole. The catalogue and an assessment of the source counts.

RODIGHIERO G. and FRANCESCHINI A.

Abstract (from CDS):

We report results from a new analysis of a deep 95 µm imaging survey with ISOPHOT on board the Infrared Space Observatory, over a ∼1deg2 area within the Lockman Hole, which extends the statistics of our previous study (Rodighiero et al., 2003MNRAS.343.1155R). Within the survey area we detect sixty-four sources with S/N>3 (roughly corresponding to a flux limit of 16mJy). Extensive simulations indicate that the sample is almost complete at S95µm≥100mJy, while the incompleteness can be quantified down to ∼30mJy. The 95µm galaxy counts reveal a steep slope at S95µm≤100mJy (α≃1.6), in excess of that expected for a non-evolving source population. In agreement with counts data from ISO at 15 and 175µm, this favours a model where the IR populations evolve both in number and luminosity densities. We finally comment on some differences found with other ISO results in this area.
