    Hi,
    It doesn't look like the date of your data (and/or the response file) is
    set correctly. Look for weird KZDATE and KZTIME headers in the sac files.
    The Julian day should be between 1 and 365 and not 0.01.

      Dear Rehman,

      As Januka has written, it appears that the date in your file header is not set correctly. I’ll add a bit to what Januka has said.

      It is good if you do some more work to understand your data and what the header variables are set to.

      First, list the date-related header variables:

      type ‘lh KZDATE’ (without the quote marks - ‘’ - and either UPPER case or lower case kzdate works; I’ll use UPPER case to make it stand out)

      That should show something like (this is from one of my sac files, yours will probably show a different date and maybe year):
      kzdate = JUL 25 (206), 2017

      If KZDATE isn’t something meaningful, then the date in the file header is wrong.

      SAC derives the variable KZDATE from two variables in the file header. Next, check those variables:

      type ‘lh NZYEAR NZJDAY’ (again without the quote marks)

      You should see something like this:
      nzyear = 2017
      nzjday = 206

      I think you will see something is wrong with nzjday and maybe nzyear.

      You will need to get those date variables set correctly before you can have SAC work with your data files.

      You must do this last step, since you have access to your data files.

      Leigh
