Fig. 1a and b. Positive a and negative b greyscale representations and c logarithmic contours of the same position/velocity array of [3 ] 5007Å profiles through LV 5 (arrowed). The continuous horizontal band is the spectrum of a field star. The bright emission from the background gas (the irregular vertical band) can be seen in a and c to contaminate the spectrum of LV 5 in the range of to . Note, however, that the velocity spike attributable to LV 5 is continuous through this range. The deep presentation in b displays the fainter emission associated with LV 5 at large negative radial velocities with respect to the systemic radial velocity. The log₁₀ contours in c are evenly spaced between 2.4 and 4.5.
