3.1.5.1. agetmat output variablesΒΆ
These are the most useful variables in the processed 5-minute averages:
data =
dday: [1x1436 double] zero-based UTC decimal day
lon: [1x1436 double] decimal longitude
lat: [1x1436 double] decimal latitude
heading: [1x1436 double] original heading, likely a gyro
amp: [50x1436 double] average signal/noise amplitude (counts)
bins: [1x50 double] bins (for convenience)
z: [50x1 double] nominal vertical depth (same as 'depth')
uabs_sm: [50x1436 double] --\ ocean velocity in earth coords
vabs_sm: [50x1436 double] --/ using smoothed navigation
uship_sm: [1x1436 double] --\ ship velocity in earth coords
vship_sm: [1x1436 double] --/ using smoothed navigation
smmps: [1x1436 double] ship speed from smoothed navigation
