Changed: Finalized and completed notation fixes to include covariance in uncertainty definitions section - Introduced q^(stat), q^(fdcf), q^(tdcf), and q^(fdcf,fit) (BARF!) - Synced notation with G1601003-v7 Reorganized Sec. III to discuss systematic error and then statistical uncertainty as opposed to a mix of both Moved discussion of Pcal systematic error identified during/post-O1 to Sec. VIII Improved beginning of section V text and Fig 5-6 captions for consistent notation Improved beginning of section VI text and Fig 7 caption for consistent notation Updated time dependent parameters of Section VII, 4th paragraph to be consistent with notation Updated Eq. 12 to be a definition that includes covariance (see G1601003-v7) Updated Eq. 13 to be correct (the final term was inverted) Improved some of the text in section VIII Updated Fig 8 to include covariance - data comes from LHO aLOG 27774 and LLO aLOG 26571
