Mismatch between design and actual value shown in MEDM screen for Stage 2 CART2ACT matrix
I have noticed that there is a mismatch between Stage-2 BSC-ISI CART2ACT basis change matrix. This is true for all the BSC-ISI chambers. The first attachment shows the designed value (https://dcc.ligo.org/DocDB/0013/T1000388/017/T1000388%20SEI%20Sensors%20Location.pdf) of CART2ACT matrix while the second and third attachments show the current matrices in ITMX (or ETMY) and ITMY (or BS/ETMX) respectively. I have cross checked that the ST2-CART2ACT matrix stored here- /ligo/svncommon/SeiSVN/seismic/BSC-ISI/Common/Basis_Change_BSC_ISI/aLIGO_BSC_ISI_BS_ITMY_ETMX.mat is in agreement with the technical document.

This was an medm error on the ST2_CART2ACT matrix. I have fixed this and commited it to the svn.
