simu.lib.context module

Section author: ECLAIRs GP team

Context is a high-level facade to centralize information and functionality on the ECLAIRs instrument required for the simulation, like:

• instrument geometry

• detector effect

• position and attitude of ECLAIRs

• earth in FOV

• range energy

• time exposure

As this is information needed by many models we use the singleton design pattern to share it.

Summary

Classes:

ContextSimulator	Defines a general simulation context for ECLAIRs observations
GlobalContextSimulator	Create global simulation context.
Observable	Designe pattern observer

class ContextSimulator

Bases: simu.lib.context.Observable

Defines a general simulation context for ECLAIRs observations

set_duration(duration)

Parameters

duration (float) – simulation time in s

set_idx_chan(idx_chan)

Set energy channel index

Parameters

idx_chan (int) – energy channel index
