**Table 2:** Observations of four epochs.
Epoch	Date	Duration (UT)	Stellar phase^a	Restoring beam (mas)^b
I	1998/09/04	08:33 $\sim$ 12:30	$\phi$ = 0.52	$\sim$ 0.6 $\times$ 0.4
II	2000/05/12,13^c	19:09 $\sim$ 01:00	$\phi$ = 0.60	$\sim$ 1.05 $\times$ 0.6
III	2000/09/05	10:01 $\sim$ 15:00	$\phi$ = 0.83	$\sim$ 0.4 $\times$ 0.2
IV	2001/01/06	02:31 $\sim$ 07:30	$\phi$ = 0.05	$\sim$ 0.5 $\times$ 0.2

^a Stellar phase, $\phi$ varies from 0 to 1 during one cycle. $\phi=0$ for visual maximum. The stellar phases given here are determined using the same method as that of Diamond & Kemball (2003) with the optical maximum at JD = 2 450 773.0 and a mean period of 557.4 days.
^b 1 mas corresponds to $0.5685\times10^{11}$ m at the assumed distance to TX Cam.
^c The Los Alamos antenna was not used.
