At: bandpass problem in subband 1/2 RCP gives reduced sensitivity.
Mp: Stowed ~ 00:35-03:00 to fix vacuum problem on mm Rx.
Cd: Power outage required running on backup power. Most scans between 01:30-02:51 were missed. Slow slew speed thereafter results in later than expected onsource time. See the flag file.
Ti: DSS36 from 02:41 to 09:10:14. RCP in all channels from 02:41-02:59. Dual pol thereafter.
Correlator: Some sources appear to have very poor a priori positions. A spectral resolution of 0.25 MHz and integration time of 1 sec has been used to compensate for this.
