Dear LMFDB team,
My name is Patrik Idén, and I am an independent mathematical
researcher based in Sweden. I am writing to ask for your
permission — or to check whether it is already covered by your
data policy — to access the Riemann zeta zero DAT files hosted at:
https://beta.lmfdb.org/riemann-zeta-zeros/data/
I have already downloaded the full dataset (all 14,580 DAT files)
for local research purposes, and I have built a small web-based
tool for exploring zero statistics:
https://pi-konsulting.se/science/tools/riemann/riemann-zero-finder-v3.html
The tool currently works with locally stored files. I would like
to extend it to support on-demand lookup of individual zeros
directly from your server, using the following approach:
- A lightweight PHP proxy on my server sends a single HTTP
Range-request (typically ~50 KB) to your server for the specific
byte range containing the requested zero, rather than downloading
the full file (up to 95 MB).
- The proxy forwards the Cookie: human=1 header as required by
your access system.
- This is a personal research tool with very limited traffic — not
a high-volume or commercial application.
I want to make sure this usage is acceptable to you and does not
place undue load on your infrastructure. I am happy to adjust the
implementation (e.g. rate limiting, caching, or mirroring the
files locally instead) based on your guidance.
I will of course
cite LMFDB as the data source in any publications or public
documentation.
And of course, if
you want, you can link to this tool and use it yourself.
I am also happy to
implement access control (e.g. password protection) on the tool
if that would help manage traffic or limit usage to authorised
users.
For transparency, I
have also set up a small diagnostic page that demonstrates
exactly how the proxy works in practice, including the
Range-request behaviour and DAT format verification:

Thank you for
maintaining this invaluable resource.
Best regards,
