What is the primary purpose of the LORAN curves on the chart?

Explanation:
LORAN curves on a chart are lines of position. Each curve represents all places that would give the same time difference measurement between a master and a slave LORAN transmitter. By plotting the curve corresponding to your measured time differences and using another curve from a different transmitter pair, you find your location at the intersection. So the primary purpose is to determine where you are on the chart. These curves aren’t used to indicate currents, measure depth, or mark shipping lanes.
