to do a backward shift you might be able to use cuterr fillz, add zeros (1sec long) to the front end of the time series

Hello,


I am trying to rotate two different components and then shift one of the components by 1 sec, I am correcting for anisotropy. I have looked through the sac manual and can not find a command to accomplish this time shift. Is it the ADD command. My understanding is that ADD would increase amplitude, not shift time. What is the command to shift a component by 1 sec ( ie move each data point forward/backward by 1 sec. )? Any help would be greatly appreciated.


Thank you,


C. Robert Lock
