The CHIP pipeline is designed to extract stellar parameters from iodine-imprinted radial velocity spectra obtained with the HIRES instrument. To accomplish this, CHIP:
- Downloads deblazed spectra from The Keck Observatory Archive (KOA)
- Prepares the spectra to be used for training of The Cannon
-
To be able to access Keck/HIRES data, you will need a KOA (Keck Observatory Archive) account. To obtain this account, you can submit a ticket by following the link provided here.
-
To use CHIP with Python, you will need to set up a Python environment with the necessary dependencies installed. We recommend using Anaconda 3 to manage your Python environment.
-
Clone this repository by entering the following into your terminal:
git clone https://github.com/jgussman/CHIP -
Change directories into the CHIP directory:
cd CHIP -
To fetch the submodules, you will need to run the following command:
git submodule update --init --recursiveThis command will pull all the data from the submodules that you just cloned. The
--initoption initializes the submodules and the--recursiveoption ensures that all submodules are included, even those nested within other submodules. -
Set up the environment required to use CHIP, using Anaconda 3.
conda env create -f install/chip-env.yml -
(Windows Users Only)
If you are using a Windows machine, you need to download geos_c.dll and move the file to the CHIP python environment's Library/bin folder. You can read more about this problem here.

You're now ready to run CHIP! Inside the tutorials directory, you will find a quick-start tutorial that will walk you through the process of using CHIP to extract stellar parameters from HIRES spectra.
