Summary of observations.

Instrument	Freq.	Median RMS	Flux scale err.
	[MHz]	mJy beam⁻¹
LOFAR LBA^a	57.7	10	10%
LOFAR HBA^b	144	0.132	10%
RACS (low)^c	887.5	0.266	7%
	943.5	0.205	7%^c
RACS (mid)^c	1367.5	0.198	7%
RACS (high)^c	1655.5	0.209	7%

Notes. For every observation we note the central observing frequency, the median RMS noise and the flux scale error taken from the relevant reference.
