siderealTime

a time, in POSIXt format, e.g. as created by
<code><a rd-options="" href="/link/as.POSIXct?package=oce&version=0.9-19" data-mini-rdoc="oce::as.POSIXct">as.POSIXct</a></code>, <code><a rd-options="" href="/link/as.POSIXlt?package=oce&version=0.9-19" data-mini-rdoc="oce::as.POSIXlt">as.POSIXlt</a></code>, or
<code><a rd-options="" href="/link/numberAsPOSIXct?package=oce&version=0.9-19" data-mini-rdoc="oce::numberAsPOSIXct">numberAsPOSIXct</a></code>.  If this is provided, the other arguments are
ignored.


Convert a POSIXt time to a sidereal time, using
the method in Chapter 7 of Meeus (1982).  The small correction
that he discusses after his equation 7.1 is not applied here.


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.

a time, in POSIXt format, e.g. as created by
<code><a rd-options='' href='as.POSIXct'>as.POSIXct</a></code>, <code><a rd-options='' href='as.POSIXlt'>as.POSIXlt</a></code>, or
<code><a rd-options='' href='numberAsPOSIXct'>numberAsPOSIXct</a></code>.  If this is provided, the other arguments are
