work around for constant = 0 in pole zeros?

Hi,  I am just wondering how I should handle instrument response deconvolution when the constant is set to zero in pole zeroes files? Is there a standard practice in this case?  Thanks !

Calling SAC commands from C program
2013-10-11 04:39:38 - 2013-10-11 16:46:44
Hello SAC users, I want to add a line something like this in a C program *sprintf(str,"cd rdtmp; sac; r *.SAC; interpolate delta 1.0; w over; quit; ../%s"); system(str);* What I want to do is that C program opens SAC and read in the files with extension ".SAC" and then interpolate the data. But when I am adding the above lines, It always stuck just after opening SAC and don't run the following commands. Any suggestion in this regard will be appreciated. Thanks, -Mohit

ttsac missing

Hi all, I seem to be missing the macro, ttsac, in MacSAC, required by split_sheba. Is this an old macro that might be only available on older versions of SAC? Many thanks, Badr Best, B. W. Rumaih SWP, Stanford (323) Rumaih-1
