[math]\displaystyle{ ^a }[/math] Typically we assume TIME for the fast-sampled microstructure channels, and eventually _SLOW or _CTD for slower sampled channels such as CTD and tilt sensors. If the application requires different time stamps for different sensors, this can be utilized like TIME_PITCH, TIME_ACC etc.
[math]\displaystyle{ ^b }[/math] Please use these examples for related sensors:
N_VIB_SENSORS for vibration (piezo-acceleration) sensors
N_ACC_SENSORS for vibration acceleration sensors
N_GRADT_SENSORS for thermistors
N_GRADC_SENSORS for microconductivity sensors
[math]\displaystyle{ ^c }[/math] number of shear sensors x number of ACC sensors
[math]\displaystyle{ ^d }[/math] number of shear sensors x number of VIB sensors
[math]\displaystyle{ ^e }[/math] This dimension is 1x1. Use, for example, for N_FFT_SEGMENTS (number_of_fft_segments), SPEC_STD (standard_deviation_uncertainty_of_shear_spectrum), and is one value for the entire analysis.
