Acoustics data production

Files

Acoustic data is stored on cloud storage, available on baikalsnr.jinr.ru:/mnt/cephfs/geometry

Directory structure

Directory structure for geometry looks like this:

cephfs/
└── geometry
    ├── 2016
    │   └── cluster0
    ├── 2017
    │   ├── cluster0
    │   └── cluster1
    └── 2018
        ├── cluster0
        ├── cluster1
        └── cluster2

Each cluster directory contains a set of acoustic files described in the next section.

File types

Filename	Contents
am-coordinates.csv	Plain text CSV file with measurements
am-coordinates.root	Files with beacon coordinates (tree per beacon)
am-coordinates.filtered.root	Files with filtered beacon coordinates (tree per beacon)
am-coordinates.joint.root	Files with beacon coordinates (single tree)
am-coordinates.joint.filtered.root	Files with filtered beacon coordinates (single tree)
am-dynamics.root	Dynamic beacon data (velocity etc)
geometry.aligned.root	Aligned beacon coordinates
geometry.guessed.root	Aligned beacon coordinates (missing data guessed)
geometry.export-linear.root	Exported OM coordinates

Files emphasized with bold font are the ones that are used for event processing.
