WDS 00251-3646 BRG 2 : NOTES

discov_num	notes	refcode
BRG 2	Like BRG 1, this stellar binary also had an asymmetric PSF, and we
	therefore calculated the photometry in the same way as for that case.
	Note that the photometry values presented here should replace those in	Brg2010
	Bergfors et al. (2010).	Jnn2012
