Examples of line profiles for the co‐added 8542 Å spectra for each offset position for NGC 2523. The error bars indicate the difference between the multiple Gaussian fit to the data and the actual data value. The dotted vertical line shows the mean of each distribution. The mean values for offset 17﹩\arcsec﹩ northwest, offset 9﹩\arcsec﹩ northwest, major axis, and offset 17﹩\arcsec﹩ southeast are ﹩3494.2\pm 124.5﹩, ﹩3519.4\pm 83.9﹩, ﹩3548.8\pm 82.2﹩, and ﹩3741.8\pm 200.9﹩ km s−1, respectively.
