Field	Contents	SI Unit Example
`frame_ID`	Reference frame identifier. (Integer, maximum 10 digits)
`unit_ID`	Unit Identifier (Integer, maximum 10 digits)
`frame_title`	Reference frame title (Character, maximum 100 characters)
`O`_x	X coordinate of frame origin O' (Real)	$[m]$ $[m]$
`O`_y	Y coordinate of frame origin O' (Real)	$[m]$ $[m]$
`O`_z	Z coordinate of frame origin O' (Real)	$[m]$ $[m]$
`X`₁	X component of frame axis $Y'$ $Y'$ (Real)
`Y`₁	Y component of frame axis $Y'$ $Y'$ (Real)
`Z`₁	Z component of frame axis $Y'$ $Y'$ (Real)
`X`₂	X component of axis $Z'$ $Z'$ ' (Real)
`Y`₂	Y component of axis $Z'$ $Z'$ (Real)
`Z`₂	Z component of axis $Z'$ $Z'$ (Real)

The reference frame identifier must be different from all skew identifiers.
The reference frame is fixed and its directions are defined by $Y'$ $Y'$ and $Z'$ $Z'$ . Vectors of arbitrary length may be given.
Input is $Y'$ $Y'$ axis and $Z'$ $Z'$ axis, but X' axis is computed as:(1)
$X^{'} = Y' Λ Z'$

$Y'$ is recomputed as: (2)
$Y^{″} = Z^{'} Λ X^{'}$

Therefore, the new reference frame is defined by $X^{'}$ , $Y^{″}$ ', and $Z'$ .
