Agilent at 6.2 GHz, 16 dB. LOs at 702 MHz, 7 dB. Coherence confirmed with tone of 819.5 MHz. These parameters are brought directly over from v256b, the previous experiment.
Recording to ATNF_V005B
tsys 1 and tsys 2 appear to have been fluctuating throughout the experiment. 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.
