For mathematical inquiries related to the implementation of one or more of the algorithms in LAL you need to contact the appropriate author(s). Authorship of algorithm implementations can be found in the license header in the source files of the library.
For further support (like installation issues on any OS, probable bugs, usage enquiries, …), send your emails to the list and we will answer as soon as we can.
If you want to stay up to date with LAL’s progress, we strongly suggest that you subscribe to our mailing list lal-announcements. This is a mailing list to receive announcements about the library’s development (e.g., new releases, bug fixes, and so on).
