I re-plotted the data sent to me a number of months ago by Klaus Henning .
This is HLine data from the 12meter Neu_Golm Radio Telescope near Berlin, Germany.
The data was recorded on 27-28 Dec 2024.
It is a 54 hour drift scan @ 4.275 mins/frame
The data was acquired via SDR#, saved with IFavg,
processed via HL3D software to remove drift and normalize to Cold_Sky scaled in dB ,
and plotted via Matlab ..
This is the Highest Resolution MW HLine Spectrum Data I have ever seen.
The Neu_Golm RT System is well designed.
