Pipeline Installation

Install Pipeline

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

  1. LSST version: v28 (as of 2025/03/17)
  2. pfs_pipe2d branch: master

Step 1: We should fetch pfs_pipe2d Gen3:

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

Step 2: We should check out to the lastest version:

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

Step 3: We should create the target folder and start the installation:

$ mkdir -p $WORKDIR/(username)/pfs/stack_28
$ cd $WORKDIR/(username)/pfs_pipe2d/bin
$ ./install_pfs.sh -t current $WORKDIR/(username)/pfs/stack_28

Install Flux Model Data

Step 1: Set up the pipe2d environment:

Source the appropriate loadLSST.* script for your shell.

$ source $WORKDIR/(username)/packages/stack_28/loadLSST.bash
$ setup pfs_pipe2d

Step 2: We should fetch the flux model data:

$ mkdir -p $WORKDIR/(username)/source/
$ cd $WORKDIR/(username)/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: We can start the installation process

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

Then we should declare the fluxmodeldata package to eups by the following command:

$ eups declare fluxmodeldata 20230608 -r /path/to/fluxmodeldata

(Optional) Individual Users: Install drp_pfs_data Package

Note

We expect that this requirement will be removed soon. It's only necessary if you will set up your own repository, specifically, for installing the "curated calibs".

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/(username)/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`)
