MgII Mass estimator:

The sigma_line estimator and L_3000 estimator is partially ready. Some test must be done to be sure that everything is clear and well defined.

located at canis: /home/arafiee/work/DR7/SMBH_MgII.sm

uses the MgII_fit.sm and fitspectrum.sm

However, there is a problem here. I am trying to estimate the sigma_instruments at MgII wavelength but I cann't extract the wavelength dispersion d from fits file. I should ask pat about this. I need to know what KEY I should use.

When I use, "specplot" in IRAF/noao/onedspec then I get a plot with flus, error and mask.
