1-6     A6        DYNSEL - Defines the times for which
                  GEODYN will use external accelerations
                  to drive the satellite. During these 
                  any accelerometer biases or attitude
                  parameters become force model parameters.

IF CARD OMITTED:  The satellite will be integrated as usual and there will be
                  no external acceleration contribution.
