That's fantastic, thank you for taking the initiative to set this up!
I had a few questions,
1) Will this work for people that are behind an institutional firewall
(e.g. at a university?), or for people that don't have a fixed IP?
2) We run some SQMs in locations that don't have an Internet
connection, and also some SQM-LUs. Is it possible for us to collect
data with our own programs and to upload the data (formatted
appropriately) to you?
3) Can you clarify whether/how the data will be available to outside
researchers? If I was to use the data I would want to download a
table rather than click on a graph.
4) Are there any plans for running quality control checks on the data?
5) What is your sampling rate? Some SQM-LEs have a noticeable 50/60Hz
oscillation that is easily and cleanly removed by averaging over many
Will you be at the Dark Sky Symposium at Osnabrück? A measurement
workshop is planned for the first day, and it would be great to be
able to discuss these and more questions. Here is the symposium
Thanks again for setting up the system and translating everything into English!
