CHE 421	This pair was not found at Chevalier's predicted location, nor was any	Che1908
	likely pair seen at other locations resulting from transposing x and y
	offsets from the plate center, or possibly sign errors in x and/or y.
	It remains the only one of his doubles from this paper not recovered.	Hrt2012b
