For some applications you need to know how fast the model correction changes with az, za so you can estimate the error you make if you evaluate the model at a "nearby" point. ... This can be useful if you want to evaluate the model correction for the current az,za but you have the az,za position of the previous second. ... This is the maximum that the az,za can move in 1 second. 3rd: The change in the az, za errors if you move the az,za position by the model error at that position. ...
