 * 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.

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
}}}
 4. 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`

 5. Source `.tcshrc` or open another `tcsh` sehll by running `tcsh`
{{{
source ~/.tcshrc
}}}

 6. 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.

 7. Consult to an IPP expert if you are stuck.
