Pointing model for Katherine after VGOS upgrade

After the receiver upgrade at Katherine, methanol maser observations (using on flexbuffke) indicated significant pointing offsets in both Az and El. After 24 hours of observing the data were combined into a MATLAB file and a new incremental pointing model was fitted to the offsets. The combined Pointing model values were then calculated and a new mdlpo.ctl file was created and tested on pcfske. The result has been a reduction in median pointing offset from 0.048 to 0.014 degrees.

The new pointing model is installed on pcfske as mdlpo.ctl with appropriate comments.
