This file contains the 195 x 195 covariance matrix. Please note that the matrix is constructed in the following way:
KLOE08(1:60;1:60)
KLOE10(61:135;61:135)
KLOE12(136:195;136:195)

To open the cov matrix, just use the following FORTRAN code:

      open(UNIT=49,FILE=
     $'./cov.mat',
     $  STATUS='OLD')
       DO I=1,195
          DO J=1,195
             read(49,*) a(i,j)
          ENDDO
       ENDDO
      close(49)
