ctools

I am using the development versions of ctools and gamma lib, downloaded yesterday (16/01/2014).
I notice that the script $CTOOLS/share/examples/python/make_binned_analysis.py whereas $CTOOLS/share/examples/python/make_unbinned_analysis.py works ok. This is due to a problem with ctbin, which I can replicate using the default parameters of ctobssim.

work@vstamate-Inspiron-1370:~/ctatools$ ctobssim
Model [${GAMMALIB}/share/models/crab.xml]
Calibration database [${GAMMALIB}/share/caldb/cta]
Instrument response function [cta_dummy_irf]
RA of pointing (degrees) (0-360) [83.63]
Dec of pointing (degrees) (-90-90) [22.01]
Radius of FOV (degrees) (0-180) [10]
Start time (MET in s) (0) [0]
End time (MET in s) (0) [1800]
