In this document, you will find a brief description of what LUCI is, how to install it (her), where to go to find examples, documentation, and more!

LUCI is a general purpose fitting pipeline built specifically with SITELLE IFU
data cubes in mind; however, if you need to fit any emission line spectra, LUCI
will be able to help! Although other codes exist, we built LUCI specifically with the user
in mind. Thanks to the clear coding practices used to create LUCI and her detailed documentation,
users can easily modify the code by changing numerical solvers. Additionally, we implemented
a Bayesian Inference algorithm using MCMC (using emcee) to derive uncertainty estimates.
We have tried to make the installation of LUCI as smooth and painless as possible; however, if you have suggestions, please reach out to us.
Below are instructions for installing on a linux distribution (only tested on Ubuntu and Pop-OS!).
- Clone this repository. I suggest cloning it in Documents or Applications.
git clone https://github.com/crhea93/LUCI.git - Enter repository wherever you cloned it.
cd LUCI - Create luci environment using the following command:
conda env create -f luci.yml. Now, whenever you wish to useLUCI, you can load the environment by simply typing the following into your terminal:conda activate luci.
If you are on a Mac, you will need to change step 3 slightly:
3. Create luci environment with conda create -n luci and then install the requirements with pip install -r requirements.txt.
**OR**
**Create** luci environment with `conda env create -f luci_macOS-11.6` which
was kindly created by Johanna Hartke.
Now you are all set to use Luci! To load the module into a python file or jupyter notebook, simply add the following lines:
import sys
sys.path.insert(0, '/the/path/to/LUCI/')
import Luci
You can quickly test that everything is working for your system by entering the LUCI directory and running pytest. You may receive some warnings, but everything should pass! If not, please let me know :)
LUCI is - of course - first and foremost, a fitting algorithm. In order to ease the pain of fitting IFU data cubes, we have built several wrappers for the fitting functions (these can be found in Luci/LuciFit.py). These functionalities include, but are not limited to: reading in a data cube in the HDF5 format (LUCI()), fitting the entire data cube (LUCI.fit_entire_cube), fitting a region or masked region of the cube (LUCI.fit_region()), extracting and fitting an integrated region (LUCI.fit_spectrum_region), creating a deep image (LUCI.create_deep_image), and building a Signal-to-Noise ratio map of the cube (LUCI.create_snr_map).
You can also access the fitting directly by circumventing the LUCI wrappers and directly accessing the fitting algorithms (Luci.LuciFitting). With this, you can fit any spectrum using the Luci.LuciFitting.fit and Luci.LuciFitting.bayes_fit algorithms. We also provide basic plotting functionality which can be found in Luci.LuciPlotting.
Examples are paramount to the success of any open source code. Therefore, we have tried to make our examples as complete as possible. That said, we surely have forgotten something! If you wish to see an example that does not exist (or for an example to be better explained), please shoot us an email or open up an issue!
All examples can be found in two locations. Read-through examples can be found on our read the docs (https://crhea93.github.io/LUCI/index.html) page while jupyter notebooks can be found in the Examples folder. I suggest starting with https://crhea93.github.io/LUCI/example_basic_lite.html.
Documentation can also be found on our read the docs (https://crhea93.github.io/LUCI/index.html) page. In addition to documentation on each function in LUCI, you can also find a description of what LUCI calculates and how she does what she does!
If you wish to contribute, that's awesome! Please shoot me an email at carter.rhea@umontreal.ca. The easiest way to get involved is to make an issue or fork the repo, make your changes, and submit a well-documented pull request.
If you have any questions about how to install, use, or modify LUCI, please send an email to Carter Rhea.
