CorryvreckanWriter

Description

Takes all digitised pixel hits and converts them into Corryvreckan pixel format. These are then written to an output file in the expected format to be read in by the reconstruction software. Will optionally write out the MC Truth information, storing the MC particle class from Corryvreckan. It is noted that the time resolution is hard-coded as 5ns for all detectors due to time structure of written out events: events of length 5ns, with a gap of 10ns in between events.

This module writes output compatible with Corryvreckan 1.0 and later.

Parameters

• file_name : Output filename (file extension .root will be appended if not present). Defaults to corryvreckanOutput.root
• geometry_file : Name of the output geometry file in the Corryvreckan format. Defaults to corryvreckanGeometry.conf
• reference: Name of the detector used as reference in the reconstruction.
• dut: List of detector names to be treated as device under test in the reconstruction. Defaults to an empty list.
• output_mctruth : Flag to write out MCParticle information for each hit. Defaults to true.
• global_timing: Flag to select global timing information to be written to the Corryvreckan file. By default, local information is written, i.e. only the local time information from the pixel hit or MCParticle in question. If enabled, the timestamp is set as the event time plus the global time information of the object with respect to the event begin. Defaults to false.

Usage

Typical usage is:

[CorryvreckanWriter]
file_name = corryvreckan
output_mctruth = true
reference = "telescope_plane0"
