Although hk is very popular, it requires very old GMT versions (GMT 4). I'm not sure if we should document it.

Yes, but we may only use it to compute RF which does not need gmt. We can revise the makefile to ignore hk.

There may exist better tools for calculating receiver functions (https://rf.readthedocs.io/en/latest/).

Yes, but we can run rfcnv in cml to compute rf, similar to distaz.

We may also recommend rf to do it in the script.

Hi, bro. Maybe I can try to write some tutorials for hk1.3 package.

@seisboy Thanks a lot. You can refer to https://seismo-learn.org/contributing/ to learn how to contribute to seismo-learn, e.g., reStructuredText basics, PR workflow. You can use the template (https://seismo-learn.org/software/template/) or any other software (e.g., https://seismo-learn.org/software/taup/). Just copy those files and revise them.

You may finish this issue with several PRs, e.g.,

• metadata page like https://seismo-learn.org/software/fk/
• introduction page like https://seismo-learn.org/software/fk/introduction/
• how to install page like https://seismo-learn.org/software/fk/install/
• more guides about how to use it. You may decide how many tutorials about how to use hk. It's better to discuss this with us before you work on this part. Actually, we don't recommend using hk because there may exist better tools (e.g., https://rf.readthedocs.io/en/latest/ and https://paudetseis.github.io/RfPy/). Meanwhile, it requires very old GMT versions (GMT 4). But I think rfcnv is very useful to calculate RF in the command line.

@seisman do you have any suggestion?
