We ran two additional Pcal lines at 333.9 Hz and 1083.3 Hz using the ENDX Pcal for about two hours during the observational ready time. This work is carried out under the WP 7093. The start time and end time are listed below:

Start Time: 1185156397

EndTime:  1185164145

We switched to commissioning for about five minutes to switch off these lines and also resumed the HIGH_FREQ_LINES guardian node which was turned off because we didn't have enough Pcal power to drive the high frequency lines and these two additional lines. We changed the starting frequency in the HIGH_FREQ_LINES guardian node to 4251.3 Hz and manually entered 4501.3 Hz as the current high frequency line.
