Properties of SMBHB candidate ACT light curves.

AGN	Freq.	span^a	S/N_sin	S/N_var
	(GHz)	(days)
PKS 2131–021	95	2084	3.4	3.8
period: 1931 d	147	2197	2.5	2.9
	225	1837	1.1	2.0

PKS J0805	95	1695	3.0	2.0
period: 1402 d	147	1708	2.2	1.6
	225	1447	1.1	1.1

Notes. S/N_sin is the amplitude of the sine relative to its residuals (Eq. C.2), and S/N_var is the rms of the residuals relative to the average flux uncertainty (Eq. C.3.)

The light curve length, ignoring gaps.
