The IMASCOD simulator is used to reproduce the imaging process of the ECLAIRs telescope of the SVOM mission.
The imaging process starts by choosing the position of a source in the sky (a gamma-ray burst for example) that will be detected by ECLAIRs. This position is expressed in Cartesian coordinates (x, y) in the field of view of the telescope, where the position x = 0, y = 0 corresponds to the lower left corner. The size of the sky image is 200×200 (x and y must not exceed 199).
Once the position is set, the photons from the source are propagated through the instrument. In the same way the background photons are added.
Once the parameters have been adjusted, click on “Run” to build the image of the detector and the image of the sky.
