ARC Echelle Spectroscopic Observation Pipeline (aesop)

Testing status Documentation Status Powered by Astropy Badge Paper

The ARC Echelle Spectroscopic Observation Pipeline, or aesop, is a high resolution spectroscopy software toolkit tailored for observations from the ARC Echelle Spectrograph (ARCES) mounted on the ARC 3.5 m Telescope at Apache Point Observatory. aesop picks up where the traditional IRAF reduction scripts leave off, offering an open development, object-oriented Pythonic analysis framework for echelle spectra.

Basic functionality of aesop includes: (1) blaze function normalization by polynomial fits to observations of early-type stars, (2) an additional/alternative robust least-squares normalization method, (3) radial velocity measurements (or offset removals) via cross-correlation with model spectra, including barycentric radial velocity calculations, (4) concatenation of multiple echelle orders into a simple 1D spectrum, and (5) approximate flux calibration.


You can install aesop from the source code by doing the following:

git clone
cd aesop
pip install .
