aligoNB for KAGRA

• The original aligoNB is developed on https://git.ligo.org/NoiseBudget/aligoNB. Because this package depends on the LIGO's computer environment, some changes are required for using in KAGRA. So TY forked it on https://git.ligo.org/yamamoto/aligoNB/-/tree/kamioka?ref_type=heads. Alteration for KAGRA is managed in kamioka branch.

Environment construction

• On Kamioka/Mitaka workstations, environment is already constructed. So you can skip this section.

  $ conda create -n aligoNB python=3.9
  $ conda activate aligoNB
  $ conda install -c conda-forge numpy scipy matplotlib nds2-client python-nds2-client gwinc gpstime astropy inspiral-range

  • Though the inspiral-range package is installed via pip in the original installation manual, it's now available on conda-forge.

Installation of aligoNB

• On the CDS workstation, aligoNB is already installed on /users/Commissioning/aligoNB.

  $ cd /path/to/somewhere
  $ git clone https://git.ligo.org/yamamoto/aligoNB.git
  $ git checkout -b kamioka origin/kamioka

Quick start

• It works only on CDS workstations in Kamioka and Mitaka.

  $ cd /users/Commissioning/aligoNB
  $ conda activate aligoNB
  $ python3 -m aligoNB -t 1369232206 -s 64 -hs k1nds2 -p 8088 K1

How to manage measurement files?

• On Local NFS disk
  • Only on-site (including Mitaka control room) people can contribute the noise budget activity.
• On Git
  • We cannot do 'git clone' soon because of too large repositories.
• On Git-LFS (same way as LIGO)
  • 50GB = $60/year?
  • For a long term usage, more large storage (= much money) is required.
