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 https://github.com/bmorris3/aesop.git cd aesop pip install .
