  zenith = NULL
)

Arguments

twilights	the full twilight data
index	the index of the current twilight
mode	the overlay mode requested by pathEdit
xlim	the horizontal limits of the map
ylim	the vertical limits of the map
twilight.contours	the contour levels to display
zenith	the solar zenith angle that defines twilight

Details

The pathEdit function allows the user to specify a function to overlay data on the map to assist is selecting an initial path.

This function overlays a contour map of the difference between the observed twilight and true time of twilight for that location and day, where positive and negative contours are shown in different colours. This can be useful is selecting an initial path for which the residuals are positive.
