WDS 12176+1427 DEA 48 AB : NOTES

discov_num	notes	refcode
DEA 48	AB + TOK 399Aa,Ab: HIP 59933 has a variable RV according to GCS. The
	32mas separation corresponds to an orbital period of ~2yr. However,
	the separations in the y and I filters are somewhat discordant;
	further confirmation is needed.	Tok2015c
