What is the purpose of assuming a source position for the GRB in the context of mapping incident photon energies?
What is the purpose of assuming a source position for the GRB in the context of mapping incident photon energies?
- To determine the duration of GRBs accurately
- To generate detector responses and map incident photon energies to observed count energies (correct)
- To understand the tradeoff between low detector response and systematics
- To study the spectrum of gamma-ray emissions
Why are NaI detectors used for standard analysis with observing angles less than 60 degrees?
Why are NaI detectors used for standard analysis with observing angles less than 60 degrees?
- Because they have a better response beyond 60 degrees
- Because they are less affected by spacecraft blockage
- Because the response is reduced beyond 60 degrees (correct)
- Because they have the highest sensitivity to gamma rays
Why is the BGO detector with the smallest viewing angle to the source used in analysis?
Why is the BGO detector with the smallest viewing angle to the source used in analysis?
- Because it has a better response at larger viewing angles
- Because it is least affected by spacecraft blockage
- Due to its reduced dependence on viewing angle compared to NaI detectors (correct)
- Due to its higher sensitivity
Why are detectors not used for analysis if portions of the spacecraft or LAT block them from viewing the source?
