COMMENT o Transformation from SAT coordinates to the equatorial (ECS)

COMMENT o Transformation from 3-dimensional SKY coordinates to the ECS 

COMMENT coordinates is specified by a rotation matrix Bij determined from 

COMMENT the sky reference position of (RA_Ref, DEC_Ref) and the roll angle 

COMMENT ROLL_Ref. 

COMMENT 

COMMENT o Bij is calculated in the same way as Aij, when euler angles 

COMMENT (phi, theta, psi) are given in (RA_Ref, 90-DEC_Ref, 90-ROLL_Ref).
