Interpolation of Instrument Response Functions for the Cherenkov Telescope Array in the Context of pyirf
No full textThe Cherenkov Telescope Array (CTA) will be the next generation ground-based
very-high-energy gamma-ray observatory, constituted by tens of Imaging
Atmospheric Cherenkov Telescopes at two sites once its construction and
commissioning are finished. Like its predecessors, CTA relies on Instrument
Response Functions (IRFs) to relate the observed and reconstructed properties
to the true ones of the primary gamma-ray photons. IRFs are needed for the
proper reconstruction of spectral and spatial information of the observed
sources and are thus among the data products issued to the observatory users.
They are derived from Monte Carlo simulations, depend on observation conditions
like the telescope pointing direction or the atmospheric transparency and can
evolve with time as hardware ages or is replaced. Producing a complete set of
IRFs from simulations for every observation taken is a time-consuming task and
not feasible when releasing data products on short timescales. Consequently,
interpolation techniques on simulated IRFs are investigated to quickly estimate
IRFs for specific observation conditions. However, as some of the IRFs
constituents are given as probability distributions, specialized methods are
needed. This contribution summarizes and compares the feasibility of multiple
approaches to interpolate IRF components in the context of the pyirf python
software package and IRFs simulated for the Large-Sized Telescope prototype
(LST-1). We will also give an overview of the current functionalities
implemented in pyirf.Comment: Presented at the 38th International Cosmic Ray Conference (ICRC

CTAO Monte Carlo Simulations - Eventlists on DL2 data level - prod5
No full textAuthor: Cherenkov Telescope Array Observatory; Cherenkov Telescope Array Consortium Contact: [email protected] The Cherenkov Telescope Array Observatory (CTAO) will be the next-generation gamma-ray observatory and is currently under construction on the island of La Palma (Spain) and near Paranal (Chile). This repository provides access to reconstructed event information (DL2- and DL1-level, simulation parameters) from Monte Carlo simulations of the CTAO Northern Array (production 5). The Monte Carlo simulations for prod5 are described in arXiv:2108.04512 , the simulation telescopes models used in the telescope simulation program sim_telarray and the configuration used in the air-shower code CORSIKA are available from the Zenodo archive for CTA Prod5 Telescope Models . MC events are calibrated and reconstructed using the ctapipe package and stored for the following data levels: - R1-MC: simulated raw data (output from sim_telarray) - DL1 (this repository) : telescope level data including images and image parameters - DL2 (this repository) : reconstructed event parameters such as energy, direction, gamma/hadron discrimination parameters - DL3: selected events with associated instrument response functions (IRFs). Preliminary DL3-IRFs are available from [here](https://doi.org/10.5281/zenodo.5499839). For a description of the file format and data model, see CTAPipe Data Model . Data set description: - using ctapipe version 0.17 ( GitHub release page , Zenodo page ) - CTAO Northern Array on La Palma for the Alpha configuration (4 large-sized telescopes, 9 mid-sized telescopes) - Zenith angles of 20 deg, telescope pointing direction north and south - Primary particles: photons, protons - For convenience, the same data is provided in a single, large file per particle type for the whole dataset which do not contain the low-level DL1 image information and a larger number of files including this information. We explicitly note that the products provided are preliminary and do not reflect the final performance of the CTA Observatory, neither are data structure or formats finalized. We also note that these data products are different to those used for the CTAO Instrument Response Functions . In cases in which the data provided in this repository are used in a research project, we ask that the following acknowledgment is added in any resulting publication: 'This research has made use of the CTA DL1 and DL2 Event lists provided by the CTA Observatory and Consortium (version prod5-DL2-release1-DL2)' and cite this repository in the reference section of your publication. We would like to thank the computing centers that provided resources for the generation of the Prod5 simulation set, click here for a list of service providers
