The stability can be read as a decimal number of the form u.s where s is the number of stable and u the number of unstable eigenvalues. So 2.03 means 3 eigenvalues with negative real parts (or in the unit circle) and 2 with positive real parts (outside the unit circle.)
For delay equations, if a root is found, its real part is included in this column rather than the stability summary since there are infinitely many possible eigenvalues.
The result of a range calculation is saved in the data array and replaces what ever was there. The value of the parameter is in the time column, the equilibria in the remaining columns and the stability info in whatever column you have specified.
