Abstract: |
We present the data reduction pipelines for the intermediate-resolution
(R=5000–10000) slit echelle spectographs MagE and FIRE operated at the 6.5-m
Magellan Baade telescope. The pipelines are implemented in IDL and
share about 80%\ of the code. We use both thorium-argon and hydroxil lines
to achieve the wavelength calibration good to 2–3 km/s across the whole
wavelength range. The final data products are sky subtracted flux calibrated
two-dimensional spectra corrected for telluric absorption. In addition, the
pipeline extracts one-dimensional spectra taking into account the extraction
profile variations along the wavelength range. The typical execution time of
about 5–7 min per object on a modern laptop allows observers to perform
the night time on-the-fly data reduction. |
