instrument
The instrument table contains ancillary calibration information. It holds nominal one frequency calibration factors for each instrument and pointers to nominal frequency-dependent calibration for an instrument. This table also holds pointers to the exact calibrations obtained by direct measurement on a particular instrument (see sensor).
