Data Reduction Frequently Asked Questions
I heard about problems with the X-shooter wavelength calibration. Where can I find more information?
Users have reported wavelength shifts in both the telluric lines for VIS and NIR data and in the sky lines of NIR data.
A report analysing these problems can be found at http://www.eso.org/sci/facilities/paranal/instruments/xshooter/doc/XS_wlc_shift_150615.pdf
