Dear all,
I am a new user of SAC and the version is 101.6. I learn it myself without any guidance from anybody else, so I get some troubles for your help.
First when I use saclst to list the DIST of epicentre, it can't work. For example:
saclst dist o a f 2039471.CI.LUC.EHZ.sac 2032039471.CI.LUC.EHZ.sac 2039471.CI.PLS.ELN.sac9471.CI.PLS.ELN.sac
2039471.CI.LUC.EHZ.sac -12345 0 7.779
2039471.CI.PLS.ELN.sac -12345 0 -12345
But when I use listhdr command, it works.
sac
r 2039471.CI.LUC.EHZ.sac 2039471.CI.PLS.ELN.sac
lh dist o a
FILE: 2039471.CI.LUC.EHZ.sac - 1
----------------------------

dist = 4.579102e+01
o = 0.000000e+00
a = 7.779000e+00

FILE: 2039471.CI.PLS.ELN.sac - 2
----------------------------

dist = 6.266563e+01
o = 0.000000e+00
I don't know why. Could anybody tell me the reason?
2, The second problem is about the oapf
I don't know what have been written in to the file. Could anyone tell me?
3, For Plotpk, there are a option of BELL. But when I set bell on, I never hear any sound of it when I click my mouse. Is there any problem?


Thanks you very much for all your kind attention and help.


Best Regards

    Hi

    saclst can list more than one header at time, as said the command line help.

    For have dist header, first you must have the station latitude and longitude and
    the lat-long for earthquake epicenter, and the LCALDA header set to TRUE, so
    sac calculate also Azimuth, back-azimuth and distance over the great circle headers.

    For oapf, read the help to learn on the format information of picks in the file oapf.
    help oapf

    HTH,

    Milton

      Hi, Milton
      Thank you for your answer. I check the LCALDA of these data and I find all the values of them are true. In fact I can get DIST and GCARC in sac with the command LISTHDR but I can't get them by SACLST. Other header variable can be obtained successfully such as the lat, Lon, depth, a, o, b ……
      For the bell, it still has no response after I confirm it is an active plot window. I use sac 101.6a on Ubuntu 12.04 LTS. I just want to know what is wrong.
      Thank you very much!

        In your sac file, the header variable DIST is undefined, so you always get
        -12345.0 with command saclst. When you start sac , and read files, if
        header variable LCALDA is true, DIST,GCARC,AZ,BAZ will be calculated
        automatically, so you can get value of DIST using LISTHDR.

        You can try to read files, then write over. After that, you can get value
        of DIST using saclst.

          Yes, Dongdong is right. When using saclst to get dist, we must read and also write the *.sac file first by the command write over. Thank you as well as Milton and januka.

          Dear all,
          I am a new user of SAC and the version is 101.6. I learn it myself without any guidance from anybody else, so I get some troubles for your help.
          First when I use saclst to list the DIST of epicentre, it can't work. For example:
          saclst dist o a f 2039471.CI.LUC.EHZ.sac 2032039471.CI.LUC.EHZ.sac 2039471.CI.PLS.ELN.sac9471.CI.PLS.ELN.sac
          2039471.CI.LUC.EHZ.sac -12345 active plot window 0 7.779
          2039471.CI.PLS.ELN.sac -12345 0 -12345
          But when I use listhdr command, it works.
          sac
          r 2039471.CI.LUC.EHZ.sac 2039471.CI.PLS.ELN.sac
          lh dist o a
          FILE: 2039471.CI.LUC.EHZ.sac - 1
          ----------------------------

          dist = 4.579102e+01
          o = 0.000000e+00
          a = 7.779000e+00

          FILE: 2039471.CI.PLS.ELN.sac - 2
          ----------------------------

          dist = 6.266563e+01
          o = 0.000000e+00
          I don't know why. Could anybody tell me the reason?
          2, The second problem is about the oapf
          I don't know what have been written in to the file. Could anyone tell me?
          3, For Plotpk, there are a option of BELL. But when I set bell on, I never hear any sound of it when I click my mouse. Is there any problem?


          Thanks you very much for all your kind attention and help.


          Best Regards
