FASER Releases

This page is intended to collect information about FASER releases used in reconstruction and simulation.

All calypso releases can be found on the Git Releases page.

Reconstruction Releases

A reconstruction release is a specific git tag of the calypso code. Tags are identified by a simple text string in the name of any reconstruction data product consisting of the lower-case r followed by a 4-digit number (e.g. r0003).

To use a tag, you should check out a local release following the calypso README instructions on gitlab. To select a specific tag, use the following command (replace r0003 with the tag you want):

git checkout reco/r0003

Then you will need to build the release in the usual way.

Prompt Reconstruction Tags

Prompt reconstruction tags use the current DB configuration, which can change.

Git Tag	Date	Release	Description
reco/p0009	26 Sep 2022	22.0.49	Second prompt reconstruction tag, used after 2022 TS1, adds noisy strip rejection and 3-station track collection.
reco/p0008	21 Jul 2022	22.0.49	First prompt reconstruction tag, almost identical to r0008, although a few additional updates and bug fixes have been included.

Reconstruction Tags

Production reconstruction tags use a fixed DB configuration, which can't change. This functionality only began with release r0009.

Git Tag	Date	Release	DB Release	Description
reco/r0014	27 Feb 2023	22.0.49	1.2.3	Updates to physics ntuple, DB update for 8b4e run and MC calo reco scale
reco/r0013	23 Jan 2023	22.0.49	1.2.1	Fix for low tracking efficiency in r0012. Also added truth information to physics ntuple.
reco/r0012	17 Jan 2023	22.0.49	1.2.1	Updated reco tag for 2022 data reprocessing and mc22. Unchanged from r0011 aside from updated conditions to fix HV bug and script updates for MC reco.
reco/r0011	1 Jan 2023	22.0.49	1.2.0	Reco tag for 2022 data reprocessing and mc22. First tag with data-based alignment and calo energy reconstruction.
reco/r0010	3 Oct 2022	22.0.49	1.1.0	Reco tag aimed at test beam reprocessing. Mainly the same as p0009 but with expanded waveform fit windows. Also first r-tag with 3-station track collection.
reco/r0009	4 Aug 2022	22.0.49	1.0.9	Third MDC reco tag, tracking geometry updates, track quality added to track output, fixed DB release enforced (1.0.9).
reco/r0008	15 Jun 2022	22.0.49	current	Second MDC reco tag, tracking updates, xAOD truth added, changed waveform status word to hit_status to avoid problems with xAOD truth variables.
reco/r0007	27 May 2022	22.0.49	current	First MDC reco tag, updated TI12 geometry, CKF tracking with material corrections, ghost suppression, and track refits, updated waveform reconstruction.
reco/r0006	16 May 2022	22.0.49	current	Tag of master before new TI12 geometry installed.
reco/r0005	12 Feb. 2022	22.0.49	current	Fix problem with Trigger waveform reconstruction in r0004. New cable map to determine waveform digitizer mapping.
reco/r0004	23 Jan. 2022	22.0.49	current	Update to simple track finder to allow multiple tracks per event, new cable map to allow reconstruction of TI12 data with IFT. Problems: does not reconstruct Trigger waveforms.
reco/r0003	11 Nov. 2021	22.0.40	current	Fixes to waveform reco and baseline determination, addition of spacepoints.
reco/r0002	2 Sep. 2021	22.0.40	current	Used in first testbeam reprocessing in early September. Minor fixes to production scripts and fix for x2 bug in raw waveform integral.
reco/r0001	19 Aug. 2021	22.0.40	current	First tag, produced after the prompt reco of the 2021 testbeam data. Updates to fix crashes on truncated events, proper waveform identifiers, and protection against events with large hit counts.

Simulation Tags

Git Tag	Date	Release	Description
sim/s0010	19 Feb 2023	20.0.49	Update for mc22 production. Calo digi fixed, workaround for tracker digi timing, updated calo calibration in DB.
sim/s0009	30 Jan 2023	20.0.49	Update for mc22 production. Calo digi speedup, lots of scripts consolidated.
sim/s0008	8 Dec 2022	22.0.49	First tag for mc22 production. Updated on 17 Dec (before mc22 started)
sim/s0007	30 Jul 2022	22.0.49	Updates to scint/calo digitization, script updates to avoid writing directly to EOS.
sim/s0006	12 Jun 2022	22.0.49	Update to handle tau and heavy flavor decays in G4 using Pythia, important for Genie samples.
sim/s0005	9 Jun 2022	22.0.49	Updated tag for FASER MDC simulation and digi samples. Many fixes including sampling issue with Foresee, fix event skipping reading hepmc files, and more single-particle samples.
sim/s0004	26 May 2022	22.0.49	Updated tag for FASER MDC simulation and digi samples. Fix problem where particle gun parameters weren't actually getting used. Needed for any single-particle samples.
sim/s0003	24 May 2022	22.0.49	Updated tag for FASER MDC simulation and digi samples. Include updates to the emulsion construction/geometry and allows digi merging. Needed for any particles going through FaserNu.
sim/s0002	20 May 2022	22.0.49	First tag for FASER MDC simulation samples. Include updates to the trench geometry and the upstream VetoNu detector.
sim/s0001	16 May 2022	22.0.49	Last tag before geometry updates. Essentially the simulation used for testbeam samples.
