Will run cal at the end of LBA to determine calibration. See V471bCdLog for more information. Results from Bruce scans (courtesy of Jamie MacCallum) below: 
 +----------------------------- 
 +Results after LBA run: SEFD @ 1650 is ~1200 Jy for both polarisations\\ 
 +SEFD @ 1370 is ~1500/1450 Jy for RCP/LCP\\ 
 +CALs are 36/42 Jy at 1650 (RCP/LCP)\\ 
 +CALs are 442/267 Jy at 1370 (RCP/LCP)\\ 
 +1370 scans were remarkably interference free.\\ 
 +1650 suffered intermittent RFI, sometimes enough to swamp Virgo. Peak amplitude of RFI pulses was ~2000 Jy\\ 
 +RFI sometimes showed time/spatial structure (appeared as regular variations during a scan but it's not clear whether it's pulsed in time or if it's something being scanned into sidelobes or the like.\\ 
 +All flux density calibrations performed using Virgo.
