imag(shadowgram, shadowgram_var, observation: common.mission.observation.EclairsObservation, config: process.imag.core.config.ImagConfiguration, proc_id, show=False)[source]¶ Imaging and Source detection main process
- processing with a loop:
- make the deconvolution of the shadowgrams image
- look for x-ray sources
- model the source
- clean the sky image
- look for other sources
sources are found based on the max in SNR image
loop stopped if the fit is not a success or if there are more than 100 sources found
the intensity of the source model is tuned based on a reference simulation with intensity=1
if there is a reference catalog, the found sources are compared to it. A source without any counterpart in the reference catalog set the new_source_flag.
build a catalog of the detected x-ray sources in the sky
Parameters: - shadowgram (2D float array) – detector images
- shadowgram_var (2D float array) – detector image variances
- observation (EclairsObservation) – observation parameters
- config – imag configuration
- proc_id (string) – id number of the process
- show (bool) – show plots: shadowgrams, first deconvolution and last deconvolution. Default=False
Rtype config: ImagConfiguration
Returns: found sources catalog, sky_images, new_source_flag
Return type:
