Query: ISOPHOT 95 micron observations in the Lockman Hole - The catalogue and
  an assessment of the source counts   We report results from a new analysis of a deep 95 micron imaging survey with
ISOPHOT on board the Infrared Space Observatory, over a ~1 square degree area
within the Lockman Hole, which extends the statistics of our previous study
(Rodighiero et al. 2003). Within the survey area we detect sixty-four sources
with S/N>3 (roughly corresponding to a flux limit of 16 mJy). Extensive
simulations indicate that the sample is almost complete at fluxes > 100 mJy,
while the incompleteness can be quantified down to ~30 mJy. The 95 micron
galaxy counts reveal a steep slope below 100 mJy (alpha~1.6), in excess of that
expected for a non-evolving source population. In agreement with counts data
from ISO at 15 and 175 micron, 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.
