DetectorImages

class DetectorImages(shadowgrams, shadowgrams_var, obs_time, energy_ranges)

Bases: object

build and save detector images for a defined observation time

constructor

Parameters:

• shadowgrams (list(2D array)) – detector images
• shadowgrams_var (list(2D array)) – detector variance images
• obs_time (float) – observation time
• energy_ranges ([[int, int]]]) – different energy ranges (in PI) to extract the images [[low_energy, high_energy],[]]

Methods Summary

background_correction()	correct the shadowgrams from the background
flat_background_correction()	correct the shadowgrams from a flat background
shapebased_background_correction()	Correct the shadowgrams from a CXB model based on the pixel solid angle image
shapebased_background_correction_fit([…])	correct the shadowgram from a shape based on the pixel solid angle image

Methods Documentation

background_correction()

correct the shadowgrams from the background

Warning

to be implemented

corrected shadowgrams is saved in self.shadowgrams_bgcorrected

flat_background_correction()

correct the shadowgrams from a flat background

the correction is made by the subtraction of the mean of the shadowgrams corrected shadowgrams is saved in self.shadowgrams_bgcorrected

shapebased_background_correction()

Correct the shadowgrams from a CXB model based on the pixel solid angle image

shapebased_background_correction_fit(solidangle_filename='/home/user/git/ECLAIRs/ecpi/common/data/instru/pixels_solid_angle.fits')

correct the shadowgram from a shape based on the pixel solid angle image

the pixel solid angle shape and an offset are fitted to the shadowgrams

corrected shadowgrams is saved in self.shadowgrams_bgcorrected

Parameters:solidangle_filename (string) – PATH/filename of the solid angle image
