Regards,
In terms of processing sequence, PSDM is performed after PSTM, and PSTM follows different algorithm than PSTM, it is also computer intensive,the velocity and the data o/p is of higher quality in areas where you expect lateral variations in velocity.

So, PSDM is not routinely done as it is expensive bcoz it requires lot of computing power.
