Observations.
	610 MHz	241 MHz	157 MHz
Bandpass & flux calibrator(s)	3C 48, 3C 147	3C 48, 3C 147	3C 48, 3C 286
Phase calibrator(s)	2225-049	2225-049	0025-260
Bandwidth	32 MHz	6 MHz^a	8 MHz
Channel width	125 kHz	125 kHz	62.5 kHz
Polarization	RR	LL	RR+LL
Sidebands	USB+LSB	USB	USB
Observation dates	3, 4, 5, 6 Sep. 2003	3, 4, 5, 6 Sep. 2003	2, 3 Jun. 2006
Integration time per visibility	16.9 s	16.9 s	16.9 s
Total duration^b	12.90 h	12.90 h	6.25 h
Beam size^c	$6.9\hbox {$^{\prime \prime }$ }\times 4.3\hbox {$^{\prime \prime }$ }$	$17.5\hbox{$^{\prime\prime}$ }\times 10.3\hbox{$^{\prime\prime}$ }$	$21.1\hbox{$^{\prime\prime}$ }\times 17.1\hbox{$^{\prime\prime}$ }$
rms noise ( $\sigma$ )	28 $\mu$ Jy beam^-1	297 $\mu$ Jy beam^-1	1.36 mJy beam^-1

^a The total bandwidth is 16 MHz but only 6 MHz is usable due to RFI.
^b On-source time (not including calibrators and slewing time).
^c Restoring beam, robust weighting parameter was set to 0.5 (Briggs 1995).
