the values of zenith and azimuth for the Sun an Moon seem to be incorrect I can't reproduce them, but more conclusively: they seem to be straight copies of the numbers for Antares :

# benchmark table from http://antares-wiki.in2p3.fr/doku.php?id=benchmarks_astro
# Position of the Moon and Sun: The following table specifies 4 observation dates. The benchmark consists in the calculation of the position of Sun and Moon
#
# in the local coordinate system
# in Equatorial Coordinates
# in Equatorial Coordinates for epoch J2000.0
# units: [deg]
# values were obtained with astro on 2010-07-15, svn revision 5525

The same is true for the values in ORCA_moon_sun_position_benchmark.csv
The tests in km3astro and aanet seem to not to test these zenith and azimuth values, either. pinging @vkulikovskiy
