Wrong spectral type
M4 instead of K5! Likely the IS NaD was mistaken for stellar D lines at low resolution. Tdall 09:35, 18 April 2006 (CLT)

Reversal?
Thomas, you often mention reversal emission lines for CaII. Could you quickly explain? It is not clear on FEROS plots... -- cedric 11:31, 18 April 2006 (CLT)


 * No, it's pretty impossible to make anything out of the DRS plots... 'Emission reversal' means that the emission line in the center of the deep absorption line has an absoption component on top of the emission. This can be very strong; in some cases making the intensity go to zero.
