(2) These are the maximum errors allowed in the final equilibrium position, for each degree of freedom. I.e. if the calculated movement is less than this, the structure is assumed to be in equilibrium. Rotations are in degrees. The default values are shown below.

Default values are:  0.02, 0.02, 0.02, 0.057, 0.057, 0.143    (G=9.81)

To take account of different unit systems Aqwa multiplies the default translation values only by G/9.81, where G is the value of gravity input in Data Category 5. These defaults will be over-written by any values input on the MERR data record, but Aqwa does not apply any additional factors; i.e. the value on the data record is the value that is used.
