The SuperSID radio telescope system<\/a> has had some coding updates. As of yesterday:
\nThe supersidpi data logger copies its data every hour to the file server
\nevery hour the file server strips the header from the CSV file, changes commas to spaces and then takes that data file and feeds it to gnuplot, which creates a graph. After that annotations are made to add a date and timestamp when generated, a few static indicators as to when sunrise sunset are generally, and then uploads it to this website.
\nwe’ll post the code a little later down.

\nAt the moment we are only monitoring the NAA station in Maine, mainly as we always get a good signal from it, less so the station in Washington state and north dakota.
\nIn the future we hope to add NOAA data points as well, ie when *they* detect SIDs.
\nOn our own Supersid page<\/a> we have our live data as well as that of the \tUniversity Louisville SID system, which we use as a reference.<\/p>\n

This is running on a linux fedora server

\n#process supsidpi data hourly
\n#new data arrives on the hour :00, do this on the :01

\ncp $datafile ..\/data1.csv
\ncd \/web\/supersid
\necho remove headers
