 ====== Yg pointing update ======
-While setting up for R1541, a large DC offset in elevation was detected using Virgo (>0.05, Hydra (~0.05) and 0857-43 (0.03). The P7 parameter in the pointing model was updated from 0.000 to 0.0400. Scans on a variety of sources indicated a good result (abs(offset)<0.02, no DC term) , with the exception of Virgo where a 0.05 degree offset was still apparent. A new pointing model is needed and the data should be collected later in this week.
+The pointing for Yarragadee has been updated following a pointing run. Tests after uploading it show good pointing (errors < 0.02 degrees). The new model parameters are
