Estimating Spectra from Photometry

Project description

# ESP (Estimating Spectra from Photometry) [![Build Status](]([![](]([![License: GPL v3](](

## Purpose ESP is a way to estimate galaxy spectra using Principal Component Analysis (PCA) and Gaussian Processes. Starting from a set of known spectra and a set of bandpasses you can predict spectra for other points in the color space of your bands both interpolating and extrapolating throughout the color space.

## Setup

ESP is pip installable. From the command line run:

pip install esphot

Now to use from python, just:

import esp

## How to Use See the [example jupyter notebook]( in the examples folder.
