Is there a way to simulated On/Off events within CTOOLS?
If not, I think it would be useful to have a cscript to perform this simulations.
It would be faster than ctobssim since you only need the On/Off regions,

Jürgen recently implemented some modifications of the response cache that improve the memory footprint of the tools (see #2893). They are already available in the development branch of ctools.
Anyway, simulating more than 100h in one go is not recommended. Typical CTA observations will last ~30 min to a few hours (the duration of the night poses a maximum limit of ~10h).
If you need to simulate long observing times you should break them down into individual pointings of ~1h each. You can find an example of how to create a pointing list in $CTOOLS/share/examples/python/make_pointings.py. Then the script csobsdef (http://cta.irap.omp.eu/ctools/users/reference_manual/csobsdef.html) will help you to convert the pointing list into an observation definition file that you can pass to ctobssim to perform the simulation.
