A couple of incorrect sign conventions were identified in the EUL2OSEM and OSEM2EUL matrices. This affects the Transverse -> SD OSEM coupling elements and Vertical -> T1T2T3 OSEM coupling elements. These elements incorrectly possessed a positive (+) rather than negative (-) sign.

This was previously corrected for at LLO (see LLO aLOG entry 4023), and has now been corrected at LHO, using a similar method.

The following H1 suspensions had their matrix elements rectified: MC1, MC2, MC3, and PR2.

Safe BURT snapshots were taken of each of the above suspensions.

The above safe snapshots were then committed to the svn.

N.B. This change should be checked for future H1 suspensions too, i.e. PRM and SR2, since HLTS's are unaffected.
