Detailed Description

template<typename ExprT1, typename ImageBinOp, typename MaskBinOp, typename VarianceBinOp>
class lsst::afw::image::pixel::BinaryExpr< ExprT1, double, ImageBinOp, MaskBinOp, VarianceBinOp >

Partial specialization of BinaryExpr when ExprT2 is a double (i.e no mask/variance part)

Todo:

Could use a traits class to handle all scalar types
