[SAC-HELP] sac scalling

[reza rezaei]

Hi every one
As you know sac changes its scale when we use fft command in it and we
should correct it with div command. (Divide into dt)
I want to use transfer to and transfer from. (Convolution and
deconvolution) I want to know does sac change its scale or not here.
Where changing scale is necessary and I have to pay attention it?
I would be please if you help me.

Thank you,
Reza
