The list of Gnuastro authors is available at the start of this book and the AUTHORS file in the source code. Here the authors wish to gratefully acknowledge the help and support they received from other people and institutions who had an indirect (not committed in the version controlled history) role in Gnuastro. The plain text file THANKS which is distributed along with the source code also contains this list.
The Japanese Ministry of Science and Technology (MEXT) scholarship for Mohammad Akhlaghi’s Masters and PhD period in Tohoku University Astronomical Institute had an instrumental role in the long term learning and planning that made the idea of Gnuastro possible. The very critical view points of Professor Takashi Ichikawa (from Tohoku University) were also instrumental in the initial ideas and creation of Gnuastro. Brandon Invergo, Karl Berry and Richard Stallman also provided very useful suggestions during the GNU evaluation process. Bob Proulx from Savannah, has kindly supported Gnuastro’s project webpage on Savannah and the management of its version controlled source server there.
We would also like to gratefully thank (in alphabetical order by family name) Marjan Akbari, Roland Bacon, Nicolas Bouché, Fernando Buitrago, Adrian Bunk, Rosa Calvi, Antonio Diaz Diaz, Stephen Hamer, Raúl Infante Sainz, Aurélien Jarno, Lee Kelvin, Mohammad-Reza Khellat, Alan Lefor, Guillaume Mahler, Francesco Montanari, William Pence, Yahya Sefidbakht, Ole Streicher, Ignacio Trujillo, David Valls-Gabaud and Christopher Willmer for their useful and constructive comments and suggestions. Finally we should thank all the (sometimes anonymous) people in various online forums which patiently answered all our small (but important) technical questions.
