New Features and Important Changes in ctools 1.3.0.dev1
5 April 2017
Introduction
------------
This document briefly summarizes the changes that have been made in this
ctools release with respect to the precedent release.
Configuration
-------------
The Python unit tests now raise exceptions instead of exiting with a non-
zero return code so that the user is not thrown out of Python after calling
ctools.test() and cscripts.test() (#1983).
If the code originates from the Git repository the configuration now switches
to developer mode which implies that the Python bindings are always built.
This solves the problem that occured for developers that could not get rid
of existing Python wrappers, even if they modified the Python interface
(#1985).
The cscripts are now copied into the bin directory upon installation instead
of creating symbolic links. This avoids problems on some VM file systems on
which creation of symbolic links does not work (#1987).
Python interface
----------------
None
Support model
-------------
The ctool::init_members() method now sets the local language to English
so that writing commas instead of dots is avoided (#1370).
ctobssim - CTA observation simulation
-------------------------------------
The tool now supports map cubes that are not overlapping with the RoI.
In this case, no spectral nodes exist and before the spectral flux()
method called in ctobssim::get_model_flux() was throwing an exception.
Now, for map cubes outside the RoI the flux is set to zero.
ctselect - CTA event selection
------------------------------
None
ctbin - CTA event binning
-------------------------
None
ctlike - Maximum likelihood fitting
-----------------------------------
None
cttsmap - Generation of Test Statistic map
------------------------------------------
None
ctskymap - CTA sky mapping
--------------------------
Any RoI is now taken into account in ctskymap so that if IRF background
subtraction is requested the counts and background maps are coherent. In
addition, the energy integration over the background template is now done
numerically so that strong variations in the background rate, such as
those occuring close to the threshold, are correctly taken into account
(#1975).
ctmodel - CTA counts cube modelling
-----------------------------------
None
ctexpcube - CTA exposure cube generation
----------------------------------------
None
ctpsfcube - CTA point spread function cube generation
-----------------------------------------------------
None
ctedispcube - CTA energy dispersion cube generation
---------------------------------------------------
None
ctbkgcube - CTA background cube generation
------------------------------------------
None
ctmapcube - CTA map cube generation
-----------------------------------
The tool now supports loading the energy binning definition from an energy
boundary FITS file, behaving now similar to the other cube tools (#1978).
ctcubemask - CTA cube filtering
-------------------------------
None
ctbutterfly - Generate butterfly diagrams
-----------------------------------------
None
ctulimit - Compute upper limit
------------------------------
None
cterror - Likelihood profile error computation
----------------------------------------------
None
cscripts
--------
The csebins script has been added that generates an energy boundaries
extension that can be used for a stacked analysis. The energy boundaries
are set as function of the variation in the effective area and background
rates of the Instrument Response Function (#1976).
