... The IC 2006 ring bears a remarkable similarity to the LGG 138 ring: the radii of the two rings, their estimated rotation speeds, and their narrow annular widths are comparable. ...
... a) the raw CCD camera image (30 s exposure); b) the spectrum produced by annular binning of the CCD image ( denotes the geocoronal line); c) the final, pure interstellar H spectrum after flat fielding, the removal of the geocoronal line, and the ...
