Octets	Key	Type	Content
12-15	referenceValue	real	Reference value (R) (IEEE 32-bit floating-point value)
16-17	binaryScaleFactor	signed	Binary scale factor (E)
18-19	decimalScaleFactor	signed	Decimal scale factor (D)
20	bitsPerValue	unsigned	Number of bits used for each packed value (field width)
21-24	realPartOf00	real	Real part of (0,0) coefficient (IEEE 32-bit floating-point value)

Notes:

( 1) Removal of the real part of (0,0) coefficient from packed data is intended to reduce the variability of the coefficients, in order to improve packing accuracy.

( 2) For some spectral representations, the (0,0) coefficient represents the mean value of the parameter represented.

( 3) Negative values of E or D shall be represented according to Regulation 92.1.5.
