The XDSPRES CL-based package for reducing OSIRIS cross-dispersed spectra

TL;DR

The paper introduces XDSPRES, a comprehensive CL-based software package designed to automate the reduction of cross-dispersed spectra from the OSIRIS instrument at SOAR, covering 1.2 to 2.35 micrometers with R ~ 1200.

Contribution

It presents a new automated reduction pipeline, XDSPRES, specifically tailored for OSIRIS cross-dispersed spectra, requiring minimal user interaction.

Findings

Automated flat field normalization with xdflat.

Complete spectral reduction pipeline with dooSiris.

Software available online for community use.

Abstract

We present a description of the CL-based package XDSPRES, which aims at being a complete reducing facility for cross-dispersed spectra taken with the Ohio State Infrared Imager/Spectrometer, as installed at the SOAR telescope. This instrument provides spectra in the range between 1.2um and 2.35um in a single exposure, with resolving power of R ~ 1200. XDSPRES consists of two tasks, namely xdflat and doosiris. The former is a completely automated code for preparing normalized flat field images from raw flat field exposures. Doosiris was designed to be a complete reduction pipeline, requiring a minimum of user interaction. General steps towards a fully reduced spectrum are explained, as well as the approach adopted by our code. The software is available to the community through the web site http://www.if.ufrgs.br/~ruschel/software.
