Technical properties of the receivers used for the OOF holography observations.

Name	Freq. range GHz	Freq. used GHz	BW GHz	T_sys K	SEFD Jy	FWHM arcsec
9 mm	30–34	32.00	4.0	68	85	24.5
7 mm	33–50	34.75	2.5	100	160	23.0

Notes. Given are the name, the possible frequency range, center frequency used, detected bandwidth (BW), system temperature (T_sys), system equivalent flux density (SEFD; S_sys), and the full width at half maximum (FWHM) of the beam.
