Cross-correlation analysis of high resolution spectroscopy (Tayph)¶
Welcome to Tayph¶
The objective of Tayph is to provide a flexible, transparent tool for the analysis of high-resolution spectroscopic time-series observations of close-in exoplanets, using a cross-correlation technique similar to what was first implemented by Snellen et al. (2010), but translated to python and expanded upon over the course of multiple papers. (Hoeijmakers et al. 2018, 2019, 2020).
The software is designed to be applied to transit observations of hot Jupiters made with echelle spectrographs at optical wavelengths. In particular, it can be applied to pipeline-reduced observations by HARPS, HARPS-N, ESPRESSO, CARMENES and to a certain extent UVES, with minimal interaction required. The software can also work on observations made with other instruments, provided that the user provides these according to a specific format (described below). Another feature is that the software can be used in conjunction with Molecfit (Smette et al., 2015) provided that the latter is properly installed.
The software is presented as a Python 3 package, following the Astropy template. It is named Tayph, which is Arabic for Spectrum, and carries additional meanings of phantom, shining and glint or glimmer. This documentation is made using the Astroplan documentation as a template.
