How to use the Lemur software
We have prepared a set of test series (asteroid and artificial satellite), on which you can compare the raw and processed by the Lemur software series of frames (see Demo Series).
Short how to use the Lemur service for processing and review results:
- download and read the documentation
- download the Lemur client – by downloading you agree with the Lemur License Agreement
- install the Lemur client:
For Windows: unpack -> run the lemur installer “lemur_x.x.x.x_win64.exe” and follow the instructions -> Lemur client shortcuts in the Windows Start menu:
For Linux: use the following command in the console terminal “sudo apt install ./lemur_x.x.x.x_amd64.deb” -> Lemur client shortcuts in the Ubuntu Activities menu:
Download the Demo Series of frames
Launch the Lemur Project Manager:
- Fill in demo server address (“lemur.instalf.pl“) and your e-mail and password to register in the system
- Create new project and add downloaded raw demo series of frames
- Start processing
Wait for the completing of processing and download the processing results
Launch the frame viewer LookSky:
- Open processing results
- Review the detected objects and tracks
- Create the appropriate reports and animation of the detected objects

Demo Series
Description:
Series of four frames, which were received in the diurnal mode.
Time interval between frames is ~15 minutes.
Sky area roughly corresponds to the main-belt asteroids area.
Exposure time is 240 s. Field of view is 100х100 arc minutes.
Processed using the default settings.
Processing result:
– 137 tracks were formed;
– 92 objects were identified with MPC catalog;
– 45 false objects.
The weakest object (MPC=e7147, Lemur=AA111A1) has magnitude 20.80 with signal-to-noise ratio 3.5.
Series with raw frames:

Description:
Series of four frames, which were received in the diurnal mode.
Time interval between frames is ~15 minutes.
Sky area roughly corresponds to the main-belt asteroids area.
Exposure time is 240 s. Field of view is 140х140 arc minutes.
Processed using the default settings.
Processing result:
– 62 tracks were formed;
– 45 objects were identified with MPC catalog;
– 17 false objects.
The weakest object (MPC=K02GJ3N, Lemur=AA50A42) has magnitude 20.00 with signal-to-noise ratio 3.2.
Series with raw frames:
series-as-20121006-4.zip (57 MB)
Description:
Series of 11 frames, which were received in the fixed telescope mode.
Time interval between frames is ~30 seconds.
TLE catalog was used, which made it possible to identify 7 out of 8 geostationaries, there were no TLE data for the 8th satellite.
Exposure time is 4 seconds. Field of view is 80х80 arc minutes.
Processed using the default settings with adding an orbit (TLE) for the object 32050, which made it possible to identify the detected object
Processing result:
– 8 tracks were formed.
Series in two minutes without break.
Series with raw frames:

Description:
Series of 42 frames, which were received in the tracking mode for satellite 23802.
Time interval between frames is ~15 seconds.
Exposure time is 4 seconds. Field of view is 80х80 arc minutes.
Processed using the default settings with adding an orbit (TLE) for the object 23802, which made it possible to identify the detected object
Processing result:
– 1 object (23802) was formed and identified.
