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.
