Mooring PR106 : CarICOOS Data Buoy A 
Latitude: 17° 51.61´N 
Longitude: 66° 31.42´W 
Location Description: Southeast of Caja de Muertos Island 
 
ADCP are expressed as U (east-west) and v (north-south) currents.
ADCP Current Measurements from z=-1m to z=-14m were average to obtain a robust barotropic tidal signal in the time series. 
Time sampling: 1 hour.

Below Harmonic Constants obtain by t_tide_v1.1, using t_demo_Ponce.m
