New Features and Important Changes in ctools 1.3.0.dev1 28 March 2017 Introduction ------------ This document briefly summarizes the changes that have been made in this ctools release with respect to the precedent release. Configuration ------------- None 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). Examples -------- None caldb ----- None models ------ None
