 +====== Pointing model for Katherine after VGOS upgrade ​ ======
 +
 +After the receiver upgrade at Katherine, methanol maser observations (using ''​methgain.sh''​ 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. ​
