variations in high resolution spectrum fringes
Posted: Fri Dec 02, 2011 9:56 pm
Hello all,
Like many people, I get sometimes get problems with fringes in my high resolution LHIRES spectra. I have now found something very strange. The strength of the fringes varies greatly with the vertical position of the binning area within the spectrum. See the attached profiles which are bins from the top and bottom half of the spectrum. I see the same effect from both the 16IC-S and 314L+ cameras.
What is going on?
