Installation

Short description

There are four python modules:

• IO: routines for parsing the parameter file and constructing useful quantities.
• Photoz_GP: the main classes for constructing a GP with the photo-z kernel, and fitting photometry.
• Photoz_kernels: the main classes for the mean function and kernel of the photo-z GP.
• Utils: various utilities, e.g., for likelihood functions.

There are two additional cython modules:

• Photoz_kernels_cy: the code computation of the photo-z kernel.
• Utils_cy: a faster multi-band likelihood function.

Installation

1. Install required packages (see requirements.txt).

Via pip or conda, e.g.,

pip install -r requirements.txt

2. Compile cython code and install module.

python setup.py build_ext --inplace
python setup.py install

4. Run the tests. Nothing should fail!

python scripts/processFilters.py tests/parametersTest.cfg
python scripts/processSEDs.py tests/parametersTest.cfg
python scripts/simulateWithSEDs.py tests/parametersTest.cfg
coverage run --source delight -m py.test

Getting Started

• Tutorial: getting started with Delight
• Tutorial: filling in missing bands
• The ./notebooks directory contains some other notebooks.
• The code in the ./scripts directory is also a good start.
