Pattern Analysis

Multi-site interference analysis

Check whether interference (RFI) events at different reference stations line up in time — evidence of a shared or repeating source. Not sure where to start? Load an example.

1 Pick stations & dates Choose one or more states/sites and a date range.
→
2 Choose a pattern e.g. events recurring at the same sidereal time.
→
3 Run it The analysis runs on the server; you can leave the page.
→
4 Read the results A timeline of matched events plus grouped coincidences.

1. Which stations and dates?

States

Type to search. Click a suggestion to add. Leave empty to include all states.

Sites

Filtered by selected states. Leave empty to include all sites in those states.

Date Range

Event Types ?

Model (CN0)

Pick which detector(s) the tests should consider. Uncheck one to find same-time matches within a single detector only.

Advanced: exclude specific dates

Drop known-bad or maintenance days from the search.

2. What pattern to look for?

Sidereal Day Alignment ?

Find events occurring at the same sidereal time ± a search window.

Advanced: search window

Window (sec) ?

Same-Second Coincidences ?

Find events recorded at the exact same UTC second by two or more different sites.

No window — matches require an exact second-level overlap. Sub-second timing is ignored.

Weekday Timing Consistency ?

Check if events repeat around the same time on selected weekdays, skipping weekends/holidays.

Advanced: weekdays, window & skipped dates

Weekdays

Mon Tue Wed Thu Fri Sat Sun

Window (sec)
