tidemAstron

Either a time in <code>POSIXct</code> format (with <code>"UTC"</code> timezone),
or an integer. In the second case, it is converted to a time with
<code><a rd-options="" href="/link/numberAsPOSIXct?package=oce&version=1.1-1" data-mini-rdoc="oce::numberAsPOSIXct">numberAsPOSIXct</a>(t,tz="UTC")</code>.
If <code>t</code> (It is very important to use <code>tz="GMT"</code> in constructing <code>t</code>.)

Do some astronomical calculations for <code><a rd-options="" href="/link/tidem?package=oce&version=1.1-1" data-mini-rdoc="oce::tidem">tidem</a></code>. This function is based directly
on <code>t_astron</code> in the <code>T_TIDE</code> Matlab package [1].

Supports the analysis of Oceanographic data, including 'ADCP'
measurements, measurements made with 'argo' floats, 'CTD' measurements,
sectional data, sea-level time series, coastline and topographic data, etc.
Provides specialized functions for calculating seawater properties such as
potential temperature in either the 'UNESCO' or 'TEOS-10' equation of state.
Produces graphical displays that conform to the conventions of the
Oceanographic literature. This package is discussed extensively in
Dan Kelley's book Oceanographic Analysis with R, published
in 2018 by 'Springer-Verlag' with ISBN 978-1-4939-8842-6.

tidemAstron function

Either a time in <code>POSIXct</code> format (with <code>"UTC"</code> timezone),
or an integer. In the second case, it is converted to a time with
<code><a rd-options='' href='numberAsPOSIXct'>numberAsPOSIXct</a>(t,tz="UTC")</code>.
If <code>t</code> (It is very important to use <code>tz="GMT"</code> in constructing <code>t</code>.)

Do some astronomical calculations for <code><a rd-options='' href='tidem'>tidem</a></code>. This function is based directly
on <code>t_astron</code> in the <code>T_TIDE</code> Matlab package [1].
