Notes. Errors in parenthesis.
This object presents confirmed variability in polarization (especially in PA).
Hutchinson et al. (1994) reported
P(V) = 1.19% (0.08%) at
, and Bhatt (1996) P(V) = 0.58% (0.11%) at
PA = 168° (5°). Our
result is more consistent with Hutchinson et al. (1994), and Rodrigues et al. (2009) with Bhatt (1996).
