Top panel: integrated profile of CIG 96, calculated from the EVLA and VLA combined HI cube (blue solid line), integrated spectrum of CIG 96 (LSRK) obtained by Haynes et al. (1998) at Green Bank 43 m (heliocentric) (pink dashed line). Our integrated spectrum shows a central velocity that is lower than the Green Bank spectrum, therefore in order to match and facilitate the comparison between the two, we have shifted the latter by −17 km s⁻¹. The green solid line is the integrated profile of the closest companion of CIG 96: NGC 864 COM01. The horizontal green dashed line sets the width at 20% of the highest flux peak (W20) for the central radio velocity computation, shown as a blue dot (V_LSRK (CIG 96)=1544.15 km s⁻¹). The vertical blue dotted line defines the two halves of the spectrum for the asymmetry parameter calculation. Bottom panel: integrated HI profile of the companion NGC 864 COM01 with a rescaled flux density for an easier visualization. The green dot sets the central velocity of this galaxy (V_LSRK (companion)=1577.90 km s⁻¹).
