=====

This code is deprecated

Generic framework for DES weak lensing processing

In the process of moving codes from the old svn package.  Also moving to new

more generic framework

python modules and sub-packages

-------------------------------

    generic

        Generic pluggable code runner

    modules

        More specific pipeline runners

    wlpipe

        The old framework

    files

        work with inputs and outputs to wl codes

    meds

        Pure python library to work with a Multi Epoch Data Structure

        Code docs here:

        https://github.com/esheldon/deswl/blob/master/deswl/meds.py

        Description of the file format here

        https://cdcvs.fnal.gov/redmine/projects/deswlwg/wiki/Multi_Epoch_Data_Structure

    To install

        # in the usual place

        python setup.py install

        # at a different prefix

        python setup.py install --prefix=/some/path

        

        # make sure it is on your PYTHONPATH

MEDS C library

--------------

This is a pure C library for working with MEDS.  Docs here

    https://github.com/esheldon/deswl/blob/master/src/meds.h

To install

    cd src

    # to install in the "usual" place.

    make install

    # to install to a different prefix

    make install prefix=/some/path install

    

    # Make sure that path is in your LIBRARY_PATH

You can also run a test from the /src directory against your

favorite cutouts file.

    ./test cutouts_file.fits

To link your code against the library, make sure to get the order correct

    CC  ... -lmeds -lcfitsio -lm ...

Making MEDS input catalogs

--------------------------

Followign the instructions above also results in a program

called make-meds-input being installed.  This is a function

to convert a fits file to an input file for the make-cutouts

program

See the docs:

    https://github.com/esheldon/deswl/blob/master/src/make-meds-input.c
