Description

MUSEpack is a python package written to support the data analyzes from Integral Field Units, specifically tailored to use datasets of the Multi Unit Spectroscopic Explorer (MUSE) mounted at UT4 of the VLT. The main purpose of MUSEpack is to measure stellar and gas radial velocities to an accuracy of 1-2km/s without the need for spectral template libraries. With strong stellar absorption lines or gas emission lines and a high-resolution spectral line library such as the NIST Atomic Spectra Database it is possible to create templates using the observed spectra, which can be cross correlated with the spectra using a Monte Carlo method.
