Spectral setup of the C-band observations with the Effelsberg 100 m radio telescope.

Spectral	Frequency	RRLs^(‡)
window	(MHz)
1	6111.0^(††)	C102α, He102α, H102α
2	4941.0	C109α, He109α, H109α
		C110α, He110α, H110α

Notes. Both spectral windows are200 MHz wide and have 65536 channels. ^(‡)α RRLs present in each spectral window. ^(††)On December 11, 2019, the band center was slightly shifted to 6109.0 MHz.
