# 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
