Total error accounts for uncorrelated statistical and background errors added in quadrature

Correlated errors NOT included in the total error
Systematic AL scale error ( multiplicative)				0.034
Systematic AL offset error (additive)				0.007
Statistical correlation between eta-symmetric pairs of AL as indicated
	a,b	-0.10
	c,d,e,f	-0.05
