The CANA package stands for "Codes for ANalysis of Asteroids". The tool was designed to perform scientific analysis for asteroids spectroscopic data.

As part of the PRIMitive Asteroids Spectroscopic Survey (PRIMASS), we have collected and analyzed hundreds of spectra of primitive asteroids among the last years. In this context, we collected the routines used for the analysis and parametrization of these data to build up a python package aimed for the asteroid community. As we are preparing to make the data library (PRIMASS-L) public to the community through Small Bodies Node of the the Planetary Data Science (PDS), it is our aim to make our science reproducible and of easy to extended.

The package is currently under development. At the moment CANA counts with:

Spectroscopic analysis tools:

• Handling tools, such as load, trim, fit (and autofit), estimate SNR, clean spectrum
• Slope calculation
• Taxonomic Classification
• Hydration band analysis

We will soon make available new parametrization methods and tools for handling Photometric data and Compositional modeling!

As Python 2.7 is coming to an end, we have updated all code for Python >=3.6, and do not provide support for Python 2.

We recommend using the Anaconda Python distribution to ensure you have all dependencies installed.

If you have any problems with the installation, check if all dependencies are installed. The dependencies can be seen below:

• Numpy
• Pandas
• Scipy
• Matplotlib
• Sklearn

If you have Anaconda or pip installed:

pip install cana-asteroids

You can get the current development version with:

pip install git+https://github.com/cana-asteroids/cana.git

See the documentation page to get started!

CANA is a open tool. You can use, adapt and modify it as wanted. But if you any of these, please cite us!
