SPARTA

SPARTA — SPectroscopic vARiabiliTy Analysis — is a collection of tools designed to analyze periodically-variable spectroscopic observations. Aimed for common astronomical uses, SPARTA facilitates analysis of single- and double-lined binaries, high-precision radial velocity extraction, and periodicity searches in complex, high dimensional data. The package is currently under active development. Comments are very welcome.

Contents:

UNICOR—an engine for the analysis of spectra, using 1-d CCF. Includes maximum-likelihood analysis of multi-order spectra, and detection of systematic shifts (ref, ref).

USuRPER—Unit Sphere Representation PERiodogram—a phase-distance correlation (PDC) based periodogram, designed for very high-dimensional data like spectra (ref).

Near-future extension plans:

Template independent radial velocity extraction (ref). Analysis of composite spectra using a 2-d CCF (ref).
