2. Software Installation

2.1. Swift - HEASoft

HEASoft developed by NASA is the major software for the Swift data reeducation, it provides several tools including xselect for data selection and xspec for spectrum fitting.

This example is for MacOS.

  • Install XQuartz for X window environment from xquartz.org.

  • Install Xcode from App Store, then by typing:

    xcode-select --install

    in the terminal to install the Command Line Tools.

  • Install gfortron from HPC.

  • Download the compiled package of HEAsoft from NASA’s HEASARC, here shows an example for Mac OS 10.11:

  • Uncompress HEAsoft to your application folder, here I put it in /Applications/heasoft/, then go to /Applications/heasoft/x86_64-apple-darwin15.0.0/BUILD_DIR, and run:

    ./configure >& config.out &

  • Create .bash_profile file in your home root folder /Users/Yourname/, add the content:

    HEADAS=/Applications/heasoft/x86_64-apple-darwin15.0.0
export HEADAS
source $HEADAS/headas-init.sh

  • Download DS9 for X Window from Smithsonian Astrophysical Observatory, Uncompress DS9 and ds9.zip to /Applications/heasoft/x86_64-apple-darwin15.0.0/bin.

  • Done.

2.3. Local CALDB Setup

Calibration database (CALDB) system stores and indexes datasets associated with the calibration of satellites.

We are going to install the local CALDB in /Applications/heasoft/CALDB_LOCAL:

  • Downloading CALDB setup files, and uncompress to /Applications/heasoft/CALDB_LOCAL.

  • Downloading CALDB Calibration Data, and uncompress to /Applications/heasoft/CALDB_LOCAL.

    The structure inside /Applications/heasoft/ will be like:

    CALDB_LOCAL
├── data
│       ├── glast
│       │       ├── lat
│       │       └── gbm

│               ├── bat

        ├── alias_config.fits
        ├── caldb.config
        ├── caldbinit.csh
        ├── caldbinit.sh
        ├── caldbinit.unix
        ├── caldbinit.vms
        └── caldbinit_iraf.unix

  • Add to ~/.bash_profile:

    ### LOCAL CALDB #########
CALDB=/Applications/heasoft/CALDB_LOCAL
export CALDB
CALDBCONFIG=$CALDB/software/tools/caldb.config
export CALDBCONFIG
CALDBALIAS=$CALDB/software/tools/alias_config.fits
export CALDBALIAS
source $CALDB/software/tools/caldbinit.sh

  • Done. We can check if the local CALDB is corrected installed by running caldbinfo, open a new terminal:

    caldbinfo INST SWIFT XRT
** caldbinfo 1.0.2
... Local CALDB appears to be set-up & accessible
** caldbinfo 1.0.2 completed successfully
