template

A small portion of the estimated template produced with the method of
<a href="https://arxiv.org/abs/2005.14083">Holzer et. al (2020)</a> on a set 
of 55 observed spectra from EXPRES.

datasets

Has various functions designed to implement the
Hermite-Gaussian Radial Velocity (HGRV) estimation approach of
Holzer et al. (2020) <arXiv:2005.14083>, which is a particular application of the radial
velocity method for detecting exoplanets. The overall approach consists
of four sequential steps, each of which has a function in this package:
(1) estimate the template spectrum with the function estimate_template(),
(2) find absorption features in the estimated template with the function
findabsorptionfeatures(), (3) fit Gaussians to the absorption features
with the function Gaussfit(), (4) apply the HGRV with simple linear
regression by calling the function hgrv(). This package is meant to be
open source. But please cite the paper Holzer et al. (2020) <arXiv:2005.14083> when
publishing results that use this package.
