 DAS profile as PSR64MHZ_N but could not keep DAS levels from varying rapidly. On advise from PI switched to the standard 64MHz_n profile. This stabilised the levels. \\ DAS profile as PSR64MHZ_N but could not keep DAS levels from varying rapidly. On advise from PI switched to the standard 64MHz_n profile. This stabilised the levels. \\
 Statistics remained about 25 (23-27) for all levels... (Cf. 33 and 17 from Mp). Could not change even after reprogramming DAS and recalibrating CABB.\\ Statistics remained about 25 (23-27) for all levels... (Cf. 33 and 17 from Mp).

-ATCA 64 MHz at the DAS should be ono-inverted. (tied array machinery adds inversion?)+Last 1/2hr stats correct by lowering the tied-array gain even further (0.08)... To be noted for the future...

 Problems with VNCs freezing and very slow networks meant that recording was slow to be started. Could not succeed with remote observing instructions... Ended up having to restart VNC server, and restart recorder_server before cdisko will start. (Could not see any free disks on cavsi2..) Problems with VNCs freezing and very slow networks meant that recording was slow to be started. Could not succeed with remote observing instructions...
