DSPIRA software contains material with several file-level license notices.
Some files specify GPL-3.0-only, others specify GPL-3.0-or-later, and retained
utility files include BSD terms. The GPL-3.0 text in LICENSE is supplied for
the GPL-covered portions of the repository; it does not replace the notices in
individual files. Those file-level notices remain the authoritative terms for
their contents.

The flowgraphs were extracted from examples/DSPIRA at gr-radio_astro commit

Later compatibility changes are recorded in the commit history.
The extracted directory history is retained in this repository. The complete
original history remains at https://github.com/WVURAIL/radio-research-software.

Their implementation bytes and original notices are retained.

The observation scripts under data-processing/ came from WVURAIL/dspira.
