VOSpec in the literature

Summary

VOSpec Multi-wavelength spectral

analysis tool developed at ESAC by ESA-VO

Create a SED with spectra from:• a wide range of different providers

registered in the VO Registry• local data (FITS, ASCII, VOT)• User-friendly (true!) SSAP

Wrapper applied on your own set of local spectra.

Graphical options:• plot colour, title and axis label

modifications• Zoom/unzoom • Automatic conversion of all units

via dimensional analysis.

VOSpec: spectral analysis functionalities

Line fitting (Gaussian, Lorentzian, Voigt).

Rest-frame (redshift correction) Spectral arithmetic and convolution

between spectra. De-reddening

• Calzetti law• Cardelli-O’Donnell law• LMC

Fit of an absorption line profile with different models (Gaussian, Lorentzian, Voigt)

Arithmetic between spectra

Continuum fitting (BB, polynomial). Integrated flux, line flux and equivalent

width calculations. Filtering

• Averaging • Convolution• Wavelet

Tuning: rebinning, reject zero points, cut spectrum.

Mirroring: line and spectrum mirroring. Bisector Wavelength-to-velocity conversion.

Polynomial fitting

Simple Spectral Access (SSA) services

SSA services accessed by VOSpec• SSA services registered in the VO

registry.• Over 30 services.• 10 within the past year which

include:• Hubble Legacy Archive (HLC)

(near-UV to near-IR)• AXIS-XMS (An XMM

International Survey – X-ray Medium Survey). 319 X-ray sources observed in optical.

• EPIC Spectra for the 2XMMi Catalogue. 96176 EPIC spectra.

• HEROS spectrograph, 6000 high resolution (R=20000) spectra, in optical.

Simple Line Access through VOSpec

VOSpec provides access to atomic and molecular line Databases (SLAP):– NIST Atomic Spectra– CHIANTI (X-rays)– CIELO (XMM-Newton)– IASD (ISO)– LERMA (molecular)– STSCI (UV)

• This allows on-the-fly identification of transitions associated to a given observed feature.

Access to Theoretical models (TSAP)

10 Theoretical Spectral Services accessed by VOSpec which include: • Evolutionary synthesis

models • Models of stellar

atmospheres, e.g. Kurucz, PGos3

• D’Alessio models of pre-main sequence stellar discs.

The VOSpec Normalization tool can be applied to both theoretical and non-calibrated spectra.

Kurucz stellar model and D’Alessio model of PMS discs fit to UV and IR spectra of HD 141569

VOSpec Summary

On-the-fly SED generation with VOSpec

- Spectra access from SSAP-compatible server

- Automatic handling of units Spectral analysis tools

- Large number of spectral analysis tools available

- Multi-component fit possible Interoperability

- VOSpec uses PLASTIC Literature

- VOSpec beginning to be used by the scientific community Usage on large sets of data

- Mainly designed to handle one source at the time → highly interactive.

- Good News: ability to handle large lists of objects about to be developed.
