Try to Reduce Section Longitude Range
Description
longitudeTighten shifts some longitudes in its first argument by 360 degrees, if doing so will reduce the overall longitude span.
Usage
longitudeTighten(section)
Arguments
section |
a section object. |
Details
This function can be helpful in cases where the CTD stations within a section
cross the cut point of the longitude convention, which otherwise might
yield ugly plots if plot,section-method() is used with xtype="longitude".
This problem does occur with CTD objects ordered by time of sampling,
but was observed in December 2020 for a GO-SHIPS dataset downloaded from
https://cchdo.ucsd.edu/data/15757/a10_1992_ct1.
Value
A section object based on its first argument, but with
longitudes shifted in its metadata slot, and also in the metadata slots
of each of the ctd objects that are stored in the station item
in its data slot.
