Hello SACexperts!
I'm trying to get SAC header info from a large number of data files and I
need some consistent formatting of the blackboard variables that are
output. So, for example, I use:
rh BK.HUMO..BH.2004.128.01.26.41.radial
setbb slon &1,stlo&
setbb slat &1,stla&
setbb sname &1,kstnm&
getbb TO stations.gmt names off newline off slon slat sname
which results in:
-122.96 42.607 HUMO
Fine. But, I'd like to extract the complete station lon/lat stored in the
header, which is actually…

with best regards.

Hi All,
I have recently updated my macOS to Catalina and I am suddenly having issues with ppk. The crosshairs lag significantly behind the mouse cursor and even overshoot and oscillate when I stop moving the mouse.
I have a Mac Pro (Late 2013) and am running Catalina 10.15 and SAC 101.6a. After updating my OS, I reinstalled XQuartz (version 2.7.11) etc.
I am using an Apple magic mouse but don’t have a lag problem with any other software (and even in SAC, the cursor is fine but the crosshairs…

Dear all,
I am working on SAC fft function to get spectrum of SAC three
component waveforms. I like to write resulted spectrum values to a
file, like the first column amplitute values and the second column
linlon (linear-logarithmic) values.
Is there any way to do this ?
Best regards,
Metin Kahraman
