Pointing model gradients


    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. To check this, Model 17 was used to compute how fast the pointing  model changes.
The steps tested were:

An az,za grid of 1 degree steps in za and 5 degree steps in az were used to evaluate the model.
The plots show the changes in the model correction for various steps (.ps) (.pdf) :
