The maps related to the radio-telescope F4KLO at La Villette (France/Paris) are presented here.
This radio-telescope is a dish (parabola)
of 10m diameter and F/D=4.33 on an equatorial mount.
It is equiped with a septum source (circular polarisation) allowing reception around the frequency 1420.4MHz which is the
hydrogen line frequency.

This map represents the sky above the site.
The orange curve enclose the area accessible by the dish.
The small purple circle indicates the position targeted by the dish.
The galactic plane and the ecliptic plane are materialized by two red curves.
These maps show the temperature of the continuous background at 1.4 MHz of the galaxy (data from [Stockert and Villa-Elisa Continuum Map] ).
The dots indicate the positions targeted by the dish during the last 24 hours distributed chronologically according to the colors of the rainbow.
The oldest positions are in blue and the most recent are in red.
The galaxy is represented in galactic coordinates using the Mollweide projection.
The galactic plane is the horizontal line bisecting the image.
At the heart of this projection lies the galactic center, home to the supermassive black hole known as Sagittarius A* (Sgr A*).
The two areas that our radiotelescope cannot observe are enclosed in grey.
One of theses areas turns around the north pole and a wider area forbids the south pole.
Additionally, the telescope's parking orientations are marked in black, while the ecliptic path is in brown.
We find the same informations, but now represented using equatorial coordinates (RA, Dec)
We now represent the Milky-Way from above with the line of sight of F4KLO (when b is near 0) on the left.
On the right, a model of the spectrum is represented (note: this spectrum is a work in progress).
