Pipeline Installation

Install Pipeline

---

The basic information of the PFS 2D DRP for this section includes:

1. LSST version: v30 (as of 2026/03/15, started from w.2026.07)
2. pfs_pipe2d branch: the latest weekly release

Step 1: Fetch pfs_pipe2d Gen3:

cd $WORKDIR/$(whoami)/
git clone http://github.com/Subaru-PFS/pfs_pipe2d

Step 2: Check out the latest version:

cd pfs_pipe2d
git checkout $(git describe --tags `git rev-list --tags --max-count=1`)

Step 3: Create the target folder and start the installation:

mkdir -p $WORKDIR/$(whoami)/pfs/stack_30
cd $WORKDIR/$(whoami)/pfs_pipe2d/bin
./install_pfs.sh -t current $WORKDIR/$(whoami)/pfs/stack_30

Install Flux Model Data

---

Step 1: Set up the pipe2d environment:

Source the appropriate loadLSST.* script for your shell.

source $WORKDIR/$(whoami)/packages/stack_30/loadLSST.bash
setup pfs_pipe2d

Step 2: Fetch the flux model data:

mkdir -p $WORKDIR/$(whoami)/source/
cd $WORKDIR/$(whoami)/source/
wget https://hscdata.mtk.nao.ac.jp/hsc_bin_dist/pfs/fluxmodeldata-ambre-20230608.tar.gz
tar xzf fluxmodeldata-ambre-20230608.tar.gz -C .

Step 3: Start the installation:

cd $WORKDIR/$(whoami)/source/fluxmodeldata-ambre-20230608
./install.py --prefix=$WORKDIR/$(whoami)/packages/

Then, declare the fluxmodeldata package to eups:

eups declare fluxmodeldata 20230608-full -t current -r /path/to/fluxmodeldata

(Optional) Individual Users: Install drp_pfs_data Package

---

If the PFS pipeline was installed for all users on a server in a public directory, e.g., $WORKDIR/pfs/, then for individual users, a local version of drp_pfs_data package -- other than the one included in the pfs_pipe2d installation above -- is needed.

We can install the local drp_pfs_data package as follows:

cd $WORKDIR/$(whoami)/packages/
git clone https://github.com/Subaru-PFS/drp_pfs_data.git --single-branch
cd drp_pfs_data
git fetch --tags
git checkout $(git describe --tags `git rev-list --tags --max-count=1`)
