Dear Mrs./Miss, Thank you for your reading. I have fixed those bugs mentioned in the last Email. In addition, I have added a parameter for xtransfer.c and transfer.c. As a result, a water_level parameter is allowed from user. Using the water_level, I compute threshold = h_max * pow(10., -water_level/20.0), which is similar to those done in obspy. The default water_level is set as 600. The involved files are as follows, /inc/icm.h, /src/icm/transfer.c, /src/icm/xtransfer.c. … [more]

Hi, I am a member of the team of ASIR Seismic (https://asirseismic.com).Is the SAC distribution suitable for UBUNTU 22.04? I have a problem compiling a program (main.f) using readbbf , setbbv and writebbf (see below) Thanks for your help, Rami Hofstetter Program main.f:------ call readbbf ('bbfile',nerr) call setbbv ('V1',v1,nerr) call writebbf ('bbfile',nerr) stopend f77 -g -c -o main.o main.f f77 -g -o ../../bin/perform main.o /usr/local/sac/lib/sacio.a /usr/bin/ld: main.o: in function… [more]

Dear Mrs. / Miss, First, please allow me to introduce myself. I'm Youshan Liu, a student at Institute of Geology and Geophysics, Chinese Academy of Sciences. Recently, I found several problems in SAC. 1. On lines 84-86 in trans.c /* Set the real part of the Frequecy Response at the Nyquist Frequency to the Amplitude of the Nyquist Freuquency */ sre[nfft - 1] = sqrt(sre[nfft - 1] * sre[nfft - 1] + sim[nfft - 1] * sim[nfft - 1]); sim[nfft - 1] = 0.0;… [more]

I have downloaded continuous waveform data of two Hi-net stations using HinetPy. But the problem is after converting the data from win32 to sac ,when I open the header of any sac file in SAC, there is no network name in it and this in turn is creating problem in station pair making in MSNoise. Furthermore, as I am a newbie in this field, I am also struggling with the response files of the stations. I have PZ response files but I want the response files to be in Station XML. I am unable to under… [more]
