#         users of Xtide or Xtide-based products.

#         This covers the use of the constants for Dutch
#         ports in the Xtide-database by designers
#         of web applications, and the use in commercial
#         tidal prediction software in which the constants 
#         themselves are not stored - i.e. the user has
#         to copy them from the Xtide-database himself.
#
#         It does NOT cover the use in commercial software
#         in which the constants are incorporated, which is
#         considered commercial use of the constants here.

# Dear David,
#
# This letter is to confirm that we are happy for you to download the
# sea level data from the British Oceanographic Data Centre website and
# use this in the generation of harmonic constants using the HarmGen
# software.  However there are a couple of things that we would politely
# ask that you do.
#
# 1.  Limit the number of harmonic constants you use in the software to
# a maximum of 40 for any port.  This should easily be enough to create
# very accurate tidal predictions as for nearly all locations, any
# harmonics left out (i.e. the 41st most significant constants onwards)
# will have amplitudes of the order of a centimetre.
#
# 2.  State that the data is derived from sea level data obtained from
# the British Oceanographic Data Centre based at the Proudman
# Oceanographic Laboratory, Liverpool.
#
# 3.  Make it clear that the predictions however are not the same as
# those computed by the Proudman Oceanographic Laboratory which uses its
# own sets of harmonic constants.
#
# 4.  Continue to make your software using the data freely available.
# Please inform us if you intend to produce a software product that you
# will be making a charge for.
#
# I hope these conditions are acceptable to you and it will be good to
# see the UK back on the map.
#
# Yours sincerely,
# Colin Bell
# Head of Applications Group
