discov_num	notes	refcode
CHE 175	There was an error in Chevalier's coordinates due to incorrect	Che1908
	plate center coordinates. In addition, there was a trigonometric
	error in deriving theta; the correct value is 180deg - theta.	Hrt2012b
	Berko's match to this pair was actually a new pair.	Bko2011c
