Challenger

  • This is the top level page that describes my Pan-STARRS adventure.
  • The ultimate goal is to provide a set of tools for accurate photometry of large galaxies.
  • Using ISP (Imaging Sky Probe) data for better evaluation of the sky background.

Data Exploration

We have a catalog of 9060 galaxies with available HI data:

Goals:

  • Measuring their g,r,i magnitudes
  • Measuring their inclinations

How to install the pipeline (IPP)

  1. Getting access to PS server
    ssh -X username@ippc??
    
  2. Download the pipeline into your home directory
    svn co http://svn.pan-starrs.ifa.hawaii.edu/repo/ipp/trunk
    
  3. To properly install the code, follow the instruction in README in the root directory of the pipeline.
    cd $TRUNK/psconfig
    

and follow INSTALL instruction. TRUNK is the path-address of the pipeline. At this stage, all necessary executable (binary) files would be compiled.

  • Note: Use "psbuild -dev -extbuild" in order to compile everything.
  • This step is fragile, as people may constantly change the codes. If the compilation process fails at some point, report the failure.
  • If you have access to a working version, do not remove it until you make sure that the newer version works as good.
    psbuild -dev -extbuild
    
  1. Modify .tcshrc in your home directory. This is where all necessary environmental variables are initialize for the shell you are using. Also see here: http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/IPP_on_ifaps1

Usually, looking at ~ipp/.tcshrc will give you an idea how to set-up your own ~/.tcshrc

  1. Source .tcshrc or open another tcsh sehll by running tcsh
    source ~/.tcshrc
    
  1. After all, you may find you cannot still run your desired IPP commands, therefore you may need to either modify your .tcshrc or compile some extra packages. Normally all packages should be installed all at once, unless some last minute changes have been introduced to some components.
  1. Consult to an IPP expert if you are stuck.
