If the rate of change of delay is linear from time A to B<br />then the delay will be quadratic from A to B as will be<br />the phase. This explains large parts of the plots you<br />sent.<br /><br />I encourage VLA users not to solve for rate because<br />it has an enormous influence on delay and phase.<br /><br />Eric Greisen<br />
