New Features and Important Changes in ctools 1.4.0 28 July 2017 Introduction ------------ This document briefly summarizes the changes that have been made in this ctools release with respect to the precedent release. Configuration ------------- The ctools header files are now installed into $(prefix)/include/ctools (#2145). Python interface ---------------- None Support model ------------- None ctobssim - CTA observation simulation ------------------------------------- None ctselect - CTA event selection ------------------------------ None ctbin - CTA event binning ------------------------- The loop over the observations was parallelized using OpenMP for faster execution. In addition, the sky directions were cached for faster computation of the weights (#1970). ctlike - Maximum likelihood fitting ----------------------------------- None cttsmap - Generation of Test Statistic map ------------------------------------------ None ctskymap - CTA sky mapping -------------------------- None ctmodel - CTA counts cube modelling ----------------------------------- The diffuse response computation for a stacked analysis require the ipix() and iend() attributes set in order to properly cache the response values, yet the ctmodel modifications introduced in version 1.3.1 did not properly set these attributes. This has been corrected (#2171). 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 ----------------------------------- None ctcubemask - CTA cube filtering ------------------------------- None ctbutterfly - Generate butterfly diagrams ----------------------------------------- None ctulimit - Compute upper limit ------------------------------ None cterror - Likelihood profile error computation ---------------------------------------------- None ctprob - Event probability computation -------------------------------------- None ctphase - Event phase computation --------------------------------- None cscripts -------- None Examples -------- None caldb ----- None models ------ None
