/*  TidelibSeldoviaCookInletAlaska.h 
  A library for calculating the current tide height at 
   Seldovia, Cook Inlet, Alaska , NOAA station ID number  9455500 
  Luke Miller, 2015-06-04 
  Compiled under Arduino 1.6.4
  https://github.com/millerlp/Tide_calculator
 Released under the GPL version 3 license.
 The harmonic constituents used here were originally derived from 
 the Center for Operational Oceanic Products and Services (CO-OPS),
 National Ocean Service (NOS), National Oceanic and Atmospheric 
 Administration, U.S.A.
 The data were originally processed by David Flater for use with XTide,
 available at http://www.flaterco.com/xtide/files.html
 The predictions from this program should not be used for navigation
 and no accuracy or warranty is given or implied for these tide predictions.
 It is highly recommended that you verify the output of these predictions
 against the relevant NOAA tide predictions online.
