For the first one, we can show that2307600100061 the covariance is the product of systematic errors. 2307600100062 For the second one, it is not true. As a consequence, 2307600100063 the covariance matrix determination of these data is 2307600100064 not so obvious. 2307600100065 STATUS (TABLE) Data received from Gregoire Kessedjian, 2307600100066 2010-11-15 2307600100067 (APRVD) Proof-read by Gregoire Kessedjian (2010-12-07) 2307600100068 HISTORY (20090825C) S.M. 2307600100069 (20100118A) S.M.Digitized data in SAN 002 - 004 added 2307600100070 (20101102A) On.
