ecpi.process.bube.core.main_bube Module

Selection and Binning, Uniformity, Background correction, Earth Occultation Correction module

This component shall perform the following tasks:
  • Select the calibrated events based on

scientific input parameters for this component. • Bin the selected calibrated events in detector images, for a set of given energy ranges and within a set of time intervals. • Create and associate the proper efficiency detector images based on the pixel life-time information. • Prepare uniformity and background images based on the same selection/binning parameters of the detector images. • Apply a non-uniformity correction and a background model subtraction to the binned detector images. The background model shall include the CXB contribution, the particle induced background and the Earth albedo contribution. • Apply a “correction” for the Earth Occultation effect in order to take into account the partial and variable occultation of the ECLAIRs field of view by the Earth. The earth passage in the FOV shall be included in the computation of the background model. • Possibly take in account (by modeling) bright source contribution at this stage (TBD). In this case input catalog will be needed (not mentioned in the input section).
