Hello!
I am interested in the instrument responses BENBOG, SANDIA, and SANDIA3.
These are built in to the TRANSFER command. Is there a way to export the
responses in some standard format so that the responses can be applied
outside of SAC? I thought about scouring the source code, but I only have
binaries.
Thanks for your help,

Dear Kimberley Schramm,
I have the original Blacknest code for the BENBOG response.
Here is the relevant snippet containing the poles and
zeros:
DATA NPOL(70)/8/,NZER(70)/4/,FRQ(70)/1.0/,
&CODE(70)/'BEN BOG '/,ACODE(70)/'BEN BOG '/,CC(70)/' '/,
+FACT(70)/1.0000/,C(70)/0.000E+00/,DEC(70)/1.0/,SAMP(70)/0.0/,
1POL(1,70)/(-10.539 , 0.0 )/,ZER(1,70)/( 0.0 , 0.0 )/,
2POL(2,70)/( -5.787 , 7.407 )/,ZER(2,70)/( 0.0 , 0.0 )/,
3POL(3,70)/( -5.787 , -7.407 )/,ZER(3,70)/( 0.0 , 0.0 )/,
4POL(4,70)/(-22.21 , 22.21 )/,ZER(4,70)/( 0.0 , 0.0 )/,
5POL(5,70)/(-22.21 ,-22.21 )/,
6POL(6,70)/( -0.06283, 0.0 )/,
7POL(7,70)/(-29.62 , 29.62 )/,
8POL(8,70)/(-29.62 ,-29.62 )/
Have you the means to work out the CONSTANT? It is not unfortunately
in the above snippet.
You can request the source code of SAC from IRIS. The rules
prevent me from sending it directly to you, but once you
have got it, the relevant subroutines are in
v101.5c/src/sac-101.5c/src/icm
Yours sincerely,
Sheila Peacock,
Blacknest.
