Description

In the conversion from flux in cm-2s-1MeV-1 to erg cm-2 s-1 the division by erg_mean*erg_mean has to be replaces by erg_mean*e_mean

I got the code from the branch but it had some additional changes (print statements, which specifically were not compliant to Python 3.x, calling of the simulation code twice, conversion of energy into log energy values). I reverted these changes so that the only change should now concern the energy correction.

Merged into devel.

#4 Updated by Knödlseder Jürgen about 9 years ago

There was another problem in cssens related to an internal quality check which led to a looping until the maximum number of iterations were exceeded. I removed now the quality check.

The following command sequence gave the output shown below (produced using the show_sensitivity.py script attached):

$ cssens debug=yes chatter=3
Calibration database [prod2] 
Instrument response function [South_50h] 
Effective exposure time (s) [180000.0] 
Radius of ROI (deg) [5.0] 
Source model [$CTOOLS/share/models/crab.xml] 
Source name [Crab] 
Lower energy limit (TeV) [0.020] 
Upper energy limit (TeV) [200.0] 199.0
Number of energy bins for differential sensitivity computation [21]
