Linux Ubuntu for Radio Astronomy: Plotting events from Muon_Data_110425@0116.txt data file from UKRAA Cosmic Watch Muon Detectors using Michiel Klaassen’s Python scripts 16/5/2025

Admin May 16, 2025 No Comments

I am surprised at just how many events there are in this file – which started 11/4/2025 : 01:16! Michiel has had difficulty converting the data into a format that…

LRO-H3 Radio Telescope (Alex Pettit H-Line Yagi) Radio observation in hydrogen line (1420MHz)

Calculating the decibel gain from my Alex Pettit Patch Yagi Antenna (1420MHz) (LRO-H3) using data collected with ezCol from Easy Radio Astronomy Software

Admin May 16, 2025 No Comments

I used a screen recorder to record time-lapse of the ezCol screen over 24 hours then choose the frame with maximum gain demonstrated for hydrogen. Calculation of decibels involved: 20…
