      Fix conjugate gradient and low pass filtering · 89c8abf6
      Florian Wittkamp authored
      This fix will reset the conjugate gradient history each time a frequency or workflow stage is switched.
      If such a stage is switched we will have a "new" objective function, thus, it makes no sense to use the old gradients for speeding up the convergence.
      This bug was the reason why the objective function could not be reduced for 2-3 iterations after a new frequency stage was appplied.

      Switched naming of frequency filter variables · dd778c01
      Florian Wittkamp authored
      I switched the naming of the variables of the frequency filtering to a more clear and easy one.
      The change affects the JSON input file and the code itself.
      The following renaming is used:
      FC_END   -> F_LOW_PASS_END
      FC_EXT   -> F_LOW_PASS_EXT
      FC       -> F_LOW_PASS
      F_HP     -> F_HIGH_PASS
      However, old JSON files will also work for now. If one of the old variables is not found, IFOS will search for the corresponding old one. This option will be removed in a future release.

      Florian Wittkamp authored
      This option is not supported anymore. Therefore I remove it from the source code.

      Offset based TK now additionally to TK File · 0904becf
      Florian Wittkamp authored
      If TRKILL_STF_OFFSET or TRKILL_OFFSET is set to 2, the offset based TraceKill will be applied in addition to the TraceKill file.
      Therefore, it is possible to exclude with TraceKill file fault receiveres and use an offset based tracekill with the build in feature at the same time.

      Offset based tracekill STF + Makefile improvement · b57d6b66
      Florian Wittkamp authored
      Implemented an offset based tracekill for STF.
      Makefile in par folder has now two new targets:
      1. make install, do an install from precompiled files
      2. make reinstall, do a clean install

      Maintenance of the Code · c7b43d05
      Florian Wittkamp authored
      Renamed function err() to declare_error().
      This was a problem, as many standard libraries also has functions err().
      I fixed a lot of compiler warnings like unused variables and uninitialised variables. However, here is a lot of work to do.

      Maintenance Makefiles · 03134342
      Florian Wittkamp authored
      (1.) IFOS Makefile
      Introduce dependencies files, which contain dependencied of each objective file. Therefore, it is possible to allow a more accurate rebuilt of the objective files.
      New standard target is IFOS2D. Moreover a new target install is available.
      (2.) Contrib
      Fixed the problem with the dependencies files if the hole IFOS folder is copied over to a different hardware architecture.
      You may now the error by ".d" files.

      Improvement to readmod · 09c5aa3d
      Florian Wittkamp authored
      The readmod functions verify now the dimension of the model file. Therefore IFOS will abort, if the model file is to small or too big.
      Moreover, the write_matrix_disk function is used to write the models to disk.

      CLEANUP: Removed unnecessary code · dc472e05
      Florian Wittkamp authored
      Bevore the FWI loop the observd data was read in and was time filtered. I think this ist not necessary, as the observed data is read in for the calculation of the residuals again.
      Therefore, I removed the code to save calculation time.

      JSON: IFOS now compatible to the JSON standard · cec16036
      Florian Wittkamp authored
      IFOS is now able to read in input files, that are formatted according the JSON standard. Nevertheless, the old files will work as well.
      In addition, I fixed some compiler warnings.

      Renaming of seismograms I/O · 28ac9cd9
      Florian Wittkamp authored
      Renaming of observed seismograms:
      SEIS_FILE_z.su -> SEIS_FILE_vz.su
      SEIS_FILE_x.su -> SEIS_FILE_vx.su
      SEIS_FILE_y.su -> SEIS_FILE_vy.su
      Either rename your observed data, or (if synthetic) rerun forward modeling, so IFOS will create observed data, which is correctly named.
