A module of the NESTOR underwater neutrino telescope was deployed at a
depth of 3800 m in order to test the overall detector performance and
particularly that of the data acquisition systems. A prolonged period of
running under stable operating conditions made it possible to measure
the cosmic ray muon flux, I-0 (.) cos(alpha)(theta), as a function of
the zenith angle theta. Measured values of index alpha and the vertical
intensity I-0

are in good agreement with previous measurements and phenomenological
predictions. (c) 2005 Elsevier B.V. All rights reserved
