#! TethysL version here initially based on automated translation from Science/grid_survey.xml
#! and then manually adjusted to take advantage of TethysL array/macro extensions.
#! With the limit of 75 waypoints, the original XML version has almost 2000 lines,
#! while just about 200 lines here.
#! Adding more waypoints here (no matter how many) would only involve adjusting the
#! Lat and Lon definitions, and the range for a macro (but no additional lines).
