Thank you. My aCcess to matlab is now more complicated, but i will try to solve it somehow.
I think it is sometimes useful to change the master. There are two reasons why I consider it:
– the temperatures. The master temperature should also be in the middle of the temperatures measured, especially in case where ktemp is neglected (forced to zero), in areas where small values of ktemp are expected, comparable to their accuracy. I think in such a case it is better to neglect the ktemp in processing, but some dilation residuals are expected and I think it is useful to let them be (close to) zero mean.
– accuracy evaluation. For standard deviation evaluation (according to Colesanti03) one needs both temporal and perpendicular baselines to have as high variance as possible, and if one starts with 30 images and updates the dataset progressively, the master is better to be changed due to the fact that it is for sure “out of center” in the time dimension.
